Widget Interaction in VR fails after first click

Hello,
I’m using 4.15 and having trouble with the widget interaction in VR.

Symptoms are that after the first click, the menu no longer takes input.

I’m using a modified VR template using the motion controller trigger to select a menu option.

Have tried Set Input Mode UI but that doesn’t affect it. Have resorted to using the Grip button to reset the menu so at least the first click can be used again.

I’ve a widget housing the menu in a blueprint in 3D space and use the widget interaction to accept input. Pawn Auto possess player is set to player 0.
Thanks.

add this to your character blueprints for every widget interaction input you have
