BUG: Documents deleted from a Faithlife Group do not appear in Deleted documents

STEPS TO REPRODUCE
SETUP: Create a document to use for this test (I used a Visual Filter).  Give it a distinctive name (to simplify documents.logos.com searches)
1) From documents.logos.com, Actions> Publish a document to a Faithlife group.
2) From the Faithlife group's Documents section, Actions> Delete the document.
3) Return to documents.logos.com, and search for it under All Documents, Deleted.

QUESTIONS/BUGS?
• Why does the document no longer appear on documents.logos.com, even in the Deleted documents list?
• Why do Actions in the Group Documents view include Delete, but not (or even instead of?) an option to simply stop sharing with that group (like "Withdraw")?
• Maybe restricting "Delete" to documents.logos.com might be safer; but is it at least restricted to the document's owner or can any Group member delete any document published to that Group?

GRACIOUS RECOVERY
Thanking the Lord that I still had an older documents.logos.com browser tab open, which still listed my lost document: clicking on the document name gave a page that (although saying "This document has been deleted.") had an Action> Undelete option.

Hope we can get a fix or at least this helps someone else out there!
