Pinning doesn't work

When i try to globally pin something and leave, nothing happens.
I waited 2 minutes after pinning it after that but no luck.
Consider this as a server side bug or client side?
Could @Chaboi_3000 or another admin solve this?

I’ve found out it was a preference, i am leaving this topic.
Pls lock @Chaboi_3000 or another TL4.
