Ralakesh's Impatience Riveted Boots

I'm playing an icicle mine assassin and using these boots to generate power/frenzy charges however quite frequently I'm losing my charges from movement as designed but once I return back to stationary they no longer appear so I either need to reload areas or pop them off my char and back on.

Seems to be when dashing or shield charging and getting stunned or knocked back? will continue to try and find out

Confirmed it has to do with being knocked back or stunned when using a dash or movement ability I also spoke with another player using the same build and he too is having the same problem
