Issue getting sizes on hover

When hovering over a folder I get the sizes for local drives, but it doesn't work for network folders (tested on admin-shares and NAS-folders within a share).

Automatic calculation is off.

Working again, thanks Leo. I used it all the ýears and a few weeks ago it suddenly didn't work anymore, thought, it was a bug. Maybe disabled by accident.
