Please see and read this to see if this will help. Dugi Guides Forum — Dugi Guides – World of Warcraft Level Guides 2010 – 2022 also to add what @Ozzi put helps as well. However its Blizz UI causing this issue. No add a side note to this, try use the default Modern new blizz ui without any modifications too it. Youll rarely get any issues. I also have some notes and a link or two that should help you more as well.
