# Fix the notices at the top of a dataset's panel

> Act on dataset panel notices: Views that need attention, files that did not fit the table, Added the same way as last time, and files waiting on your input.

Some datasets show a card above the Overview in their panel, under **Data** in the left sidebar. Each card says what happened and offers the fix. Anyone with access to the project sees them; with view-only access, the fixes that change data are greyed out.

## Views that need attention

When a View on the dataset is failing, out of date, or not syncing, a banner explains it:

| Message | What it means |
| --- | --- |
| "A task failed on the last run." | A step in the View's pipeline failed. Click **Fix failing task** to open it. See [Fix a failing step](https://mammoth.io/docs/learn/clean-and-shape/fix-a-failing-step/). |
| "New data has landed since this view last ran." (or "3 batches have landed since this view last ran.") | The dataset has newer data than the View has processed. On a dataset with one View, this shows on the **Settings & history** door instead. |
| "Auto-sync is off, so this view stays frozen when the dataset refreshes." | The View's Auto-sync is off. See [How Auto-sync works](https://mammoth.io/docs/learn/organise/view-auto-sync/#how-auto-sync-works). |

On a dataset with several Views, the banner reads, for example, **2 of 4 views need attention**, with counts such as **1 failing** and **1 sync off**. **Show me** lists them when more than one View needs you. In the list, each View shows a chip: **Failing**, **Out of date**, **Sync off** or **Updating**.

## Files that did not fit the table

A card such as "2 files arrived and did not fit the table." also says how many rows the dataset still holds from before. Its button names the fix:

| Button | What it fixes |
| --- | --- |
| **Match the columns** | The file's columns don't match the dataset's |
| **Pick the tab** | The workbook has several tabs, and Mammoth needs to know which one to read |
| **Enter the password** | The file is password-protected |
| **Review the file** | The file needs a check before it can be added |

## Added the same way as last time

A new workbook can go in automatically using the saved tab and reading (see [Choose how new files are added](https://mammoth.io/docs/learn/organise/dataset-settings/#choose-how-new-files-are-added)). The card **Added the same way as last time** gives the number of rows and the tab they came from.

- **See how** opens **Settings & history**.
- **Undo** asks, for example, "Take out 120 rows?". **Take them out** removes that workbook's rows. This can't be reversed.
- **Undo** is not offered when the dataset replaces all data.

## Share it through datasets

This card can appear if you manage the workspace's AI Agent settings and people outside the project ask about its folders. It lists each shared folder with **Has it** or **Not yet**. **Add it for 3 folders** hands the job to the AI Agent, which makes a filtered copy of the dataset for each folder that lacks it; **Not now** hides the card. The AI Agent is available on Enterprise plans.

## Resolve a file that needs your input

A file waiting on a password, a tab to pick, or a reading to choose opens a smaller panel: "This file needs your input before it can be processed." Its actions are **Resolve** (opens the fix), **Explore** (the raw rows), **Replace the file** and **Rename** (once it is a dataset), **Move to**, and **Move to trash** or **Delete permanently**. See [Upload files](https://mammoth.io/docs/learn/get-data-in/upload-files/).
