6.2 Beta colours

Im just trying 6.2 Beta. Glad the ‘chain link’ icon has gone.
Slight problem. Ive noticed that when trying to add colours to tracks in editing in the database, the custom colours from the previous version have not been saved. Im sure when ive updated from other versions the custom colours in the editing window had transferred across. Note this is for adding or editing the colour pallet. Colours already set do not have a problem.

They should be in the preferences.ini config file. Check if it has been copied over correctly when you migrated the config.
