Single/Multiplayer, Touch & Vive blueprint only Template

Hi I’ve downloaded your template (great work btw!) Although I’m running into some issues regarding the grab and custom hand poses. In the BP I can’t seem to position any of the fingers, changing the values does nothing. Even the preset hand poses have been reset to default so this means when I try to grab anything in the VR Preview the objects just disappear. Guidance on this would be appreciated from you or anyone else! Thanks!
