Prop Glitches When Posing them Through Brio

[Morgana-96]

I occasionally use both Brio and Anamnesis for gposing. Recently, I've been trying to use Brio's props selection in my poses. However, I've been running into an issue where the prop will randomly vanish while I'm in the middle of positioning it, or will begin glitching out/shaking (it will continue to move even if I use the freeze/pause features in Brio & Anamnesis). Is it an overall glitch, or something I need to fix in my own settings?
