macOS Finder sidebar plain-grey

Hi all,

after moving to 2.5.x client the icon in the Finder sidebar has actually become of a boring grey and even deleting the files in the local Application Support folder didn’t help that much.


The issue takes place on HighSierra 10.13.6 but don’t know if any other macOS version is affected and current client is 2.5.1

Any idea on getting it fixed?
Cheers, Riccardo
