Hello,
Per the latest T4 Blank BS5 and T4 System Plugin update - it is impossible to change ordering of columns in the mega menu builder. You can drag positions and save - but no changes appear on front-end and after saving the positions revert. Global checkin, cache do not solve the issue.
Also, column titles do not change once edited. The old title remains on the back-end UI.
This is occuring on all our updated sites so I am sure you can check locally if you have the most recent versions installed. Please advise.
