You can disable vamX expressions by opening the vamX Menu -> Plugins -> 2nd page -> Configure Head Control & Expressions -> vamX Expressions OFF. Let me know if that solves your issue. If you have VaM Creator, you can also edit the __vamX Plugin atom -> Plugins tab -> plugin#0_vamX.CHOOSE_VAMX_FEATURES press Open Custom UI... -> Uncheck various vamX features to disable them.
Also, if you are using looks or scenes from the hub, and find that vamX specifically distorts that look, send me a message with what looks / scenes you are having issues with, and perhaps I can improve it in future versions of vamX.
