When I go through blocks in vanish, I immediately fall.

So when I go through blocks in vanish on a server, I immediately start falling which is super annoying. There is no bug on the server for this and the only possible issue for it is to be a Minecraft bug. Please fix this as it is super annoying and inconvenient. Clip below.

 

Also, I have made this as private because of me being a zeqa staff member, therefore not wanting to leak anything related to it
