Delete a version of a proof while keeping prior versions intact

Hi @bunny1 

You can delete a version of a proof.

To do this:

1. Go to the project, task, or issue that contains the proof, then select Documents.Find the proof you need.

2. In the Version area in the Summary, click the version, then click Delete in the drop-down list that appears. The Delete option is visible only if there are at least two versions.

I hope that is helpful for you.
