Rotating Hot Bar

[vc50er]

I am running Profit. Three times now I have had hotbar #5 rotate by itself to Hotbar #10. During combat.

Does anyone have any idear how that could happen? I use a large macro that executes from a key. ('=') on Hotbar #5. That position on Hotbar #10 is evac. The position before ('-') has a large macro for AOE's. On Hotbar #10 it is a small macro for LFG.

In other words it's a disaster....

I hope someone can help me with this.
