Hotkeys randomly moving to right click?

I’ve been playing for 2 hours today and every time I use a hotkey skill it binds to my right click button.
So for example - I have energy shield bound to A. I press A and the skill changes my right click mouse button and it becomes energy shield instead of frozen orb.

I’ve checked my settings as there is a scroll through skills button (mouse wheel) but I got rid of that.
Is anyone else experiencing this? It’s only happened today and I played it yesterday before servers went down.

Since this feature is availible on pc, this happens to me maybe every 30-60 minutes.
Must everytime change it back, not easy in a diarun sometimes.
And i cant find a specific trigger for it.

I think it has something to do with using spells in town…

happened to me with holy shield. when i cast it in town by pressing f-buttons.

I honestly thought that, but I cast energy shield and frozen armour whilst in battle alot of the times which is where it happens. It did happen though once in town where it key bound to my right click using the F and A buttons.
