VR Teleportation Anomoly

Hi Guys, I hope you can assist me as I am Going crazy. As you can see from my little video when I teleport on the carpet anywhere like normal. As soon as I go anywhere on my set it’s almost like you drop in. Initially I thought I was jumping, thought it might be bindings but it only happends on the set not the carpet. I have checked all the usual suspects everything looks normal.

Thanks in advance !
