Random folders renamed with (W) or (L) at end of name

Hi All,

Has anyone come across this behaviour or similar (running nextcloud 12.0.4 on ubuntu)…

A user reports:

  • There are duplicate folders that do not have all of the same contents.
  • Strange letters in brackets have been added to some folders e.g. (L), (W)

There’s a screenshot on this link…

Any idea what might cause the (W) and (L) being added to folder names?

Thanks
