Unshare option is missing for normal users

Hi - I am admin of NextCloud and when I share a file/folder via email I have an option to unshare. When a normal user share a folder/file he only sees ‘can edit’ checkbox. There is no 3 dots where you can unshare it. Any suggestions?

I have seen a similar behaviour between my laptop and my desktop.

The laptop and Desktop are running the same build of Linux Mint and the issue is seen with Firefox and Chromium.

Having shared an object on my Desktop I can see both Can Edit and share options . While on my laptop I only see Can Edit. As a result I can’t un-share from the laptop.

Presumably a screen resolution issue as the desktop is running 1920x200 while the laptop is running 1366x768.
