Virtual reality training : AT mine bug

Hi I am playing through the VR training mode and have discovered that upon deactivating the AT mine, I can pick up the mine but it does not get added to my inventory. I have also tried to pick up the mines from the ammo box but again nothing gets added.

Possibly a bug with the new patch unless I am missing something, although I have checked a youtube video of the training and I am doing the same thing as the guy in the video.

Edit : Also a problem on the next stage for the AT launcher. I cannot pick up any rockets for the launcher thus making this stage uncompletable also.

A restart of the game fixed the issue I was having
