Hello,

That's a good question! Does the size in the top right change when the page
is reloaded? Are these datasets copied from another history?

How are you purging the datasets? As Dannon mentioned, if you click the 'X'
button on the dataset it will 'mark' the dataset as deleted. To permanently
deleted the datasets (or 'purge' them), you can:

1. Mark them deleted using the 'X' button on the dataset,
2. Then from the history options menu (the button that looks like a gear at
the top of the history), select 'Include deleted datasets'. This will make
the dataset you marked as deleted visible in the history again.
3. In the deleted dataset you'll see a yellow box explaining that the
history has been deleted and showing two links: one for undeleting the
dataset (which will undo the deletion of the dataset) and one for
immediately removing it from disk - this link will purge the dataset. Click
the second link.

You can hide the deleted datasets again by clicking: history options menu
-> 'Include deleted datasets' again.

If you do the above, does the size in the top right change or still remain
the same?

Let me know if you need more info,
Carl
