Removing download

Hello dear community,

I can’t find a way to remove download (or “purge” in the DEVONthink terminology) in the DTTG 4 on my iPad:

particularly, I have these images stored in the Inbox in one of the Databases (not Global Inbox). The Download Files setting for this database is set to “On Demand”.

Interestingly, PDF documents in the same location do have “Purge” option.
