Questions 2 : I don't know if this is a bug
If I set up the priest's StanceBar, the StanceBar changes when I switch to the druid, without left alignment

So I had to re-create a druid-friendly configuration, but when I switched specializations, StanceBar changed again, and it was still left-aligned
