Visual Icon bug Warlock

https://imgur.com/a/op2EXFE
This just started about the time the Hallows End event started. For some reason any Destro spell icons (and 1Affli spell "Howl of Terror") icons are not visible on cast bars. /reload does nothing, have deleted cache and wtf files, problem still exists. I found some old threads regarding this issue but none of the suggested fixes seemed to work in this case. Any help would be greatly appreciated.

Delete your Cache folder but be ready to afk few minutes in dalaran or where ever until the client manages to rebuild the cache you deleted.
