There was another person having pretty much the same problem in a thread a few days ago. Check Udiza’s response here and see if anything they said might apply to you. I’m not sure if it will help because the OP of that thread never replied, but it’s a good starting point.
The fact that more than one person has posted about it now though makes me wonder if some sort of bug hasn’t manifested, so if Udiza’s post doesn’t help I’d recommend posting a thread over in bug reports as well so it can get on blizz’s radar.
