Lost retainer MCH 60 progress while trying to switch job to GNB

[Insertusernamehere]

Thanks for answer.

Here is problem I have experienced.

I have BRD 50 MCH 80 GNB 80 jobs:

I level retainer to BRD 50 and changed to MCH until 60 level and tried to change GNB whole progress gone.
Now I have only 1 option level 1 bard on retainer job choice. I am not sure what I did wrong but clearly something wrong
