Collabora escape and go back (browser) bugs

Hi.
I have quite a few problems with collabora… when I edit an .odt, .ods, .odp files and exit, directory is not “aligned” anymore… if I click on the document, I cannot see download and delete buttons in full, as seen below:

Any help would be appreciated.
