I have this problem when I set up the sorting of a fence by 'Last modified' / REverse Order, so that the lastest item added to the fence shows up in the bottom position.
The sorting revert to default for I do not know what reason. After reading a solution to this issue, I tried the solution to rename/ recreate a fence but to no avail.
I am running the latest version on a recently formatted/ clean state machine. (Win 10 64 bit Home)
Your help is much appreciated.
