Groups change the order on it's own

I programmed the groups starting with pianos. Once I reopen the project the order is now changed , it starts with Perc. The same for outs. Can’t see why actually. Needless to say it is not possible to rearranger the order

… yes, sorry, that’s a bug. We’ll fix it.
