Its not randomized for final version.
Try to think of it as just filling up the slots, because the functionality to work propper as everybody wants it to be, is or has not been programmed yet.
But game can be played wiith current state, obviously annyoing though.
The new UI Interface is so much better now then before, but ofc theres some things/infos missing in it we had before and the new slot Quickbar options arent perfected yet.
All will be ironed out in time.
Meantime we fill Larian in with information what works and what does not.
