FPS forcefully capped after downloading BTS Settings

Hello! Recently, I’ve wanted to have lower ping in servers but it’s random on which one you land in. So, I downloaded BTS Settings, an app extension that allows me to see the region of servers so I can pick ones that are closest to me.

This worked perfectly, but I had another problem. My FPS was now capped at 60 (despite being allowed to reach a max of 144 in the In-Game Settings). I removed the extension but it’s still stuck at 60 FPS. Any help?

This weird FPS thing does not effect Roblox studio.

Edit: When I first join my FPS is at 144 but then is suddenly shoved down to 60.
