Hi Brad, thank you for posting in the Q&A forum.
I would like to confirm a few things with you:
- Do you see this behavior when trying to edit other documents (Word/Excel, etc.) in this library?
- Do you have unique permissions on the issued document that might conflict with your current permission?
- Does this issue happen only to you or also to other groups members?
- Did you see any error message in PowerPoint (client/Online) when you lose SharePoint permissions? What if you open the file in Read-Only mode?
SharePoint permissions do not get removed automatically on mentioned actions.
I would suggest you remove this account from the SharePoint group and grant it direct access to this site/library/document instead. Check if the issue persists after that.

Chelsea,
Thanks again for the questions and sorry for the delayed response. I was able to attempt to troubleshoot but am having the same issue.
I am fairly confident it has to do with my cert. I will have access and I can edit it when I click the three dots and select edit in PPT, but when I click on the link it asks for my auth and I select the only cert (and the correct one) and then I get removed from all the admin groups and I go back to only having read permissions.
