Tokens on GM layer are visible to players

Hello, The tokens I place on the GM layer are visible to the players. Does anybody knows of a way to solve this issue? I've been using Roll20 for over a year now and this is the first time it happened...

Are any of the players co-gm's that are logged in as gm's?  Our group often assigns multiple player(s) co-gm privileges to let them help with certain "housekeeping" tasks or to occasionally gm. In such games, we remind the table at the start of our sessions to make sure they are logged in as players to prevent any spoilers.

No, not actually... But thanks for the reply, anyway. It definitively was a possible cause for that.

Are you using any extensions that might be interfering? Testing in a private browsing window is a good way to rule out most interactions like that. Also, you can test with a  Dummy Account  to verify any changes without having to depend on player availability.

I'm going to run the tests you suggested and will report back! Thanks in advance ;)
