Issues with something

Please consider using the “What are you working on currently?” topic!
Didn’t know what category to put this on, but I need help with something that is happening.https://gyazo.com/d5f7ed55441c8a219350dd5f4a45ba80
The thing where I am sitting in the wrong direction is not the problem.

Can you explain what the issue is?

Also next time please upload the video on youtube (or gyazo, etc.) instead of putting it as a wmv file.

Yes, I know ROBLOX just has to make it a download file. But I came up with a better explanation, I have a pulley lift thing or whatever it is called, but when I sit in it it pops out of it’s place.

Tuns out I just had to turn off massless.
