Data Toggle Not Working

On Note 10+, strange issue with the "Cell Data" task 

Indeed, the task run succefully, but the only effect is visual change of the button in the notification bar parameters. Cell data still remain active / inactive as there is no change.

Due to the strange issue, here is a video for the problem : https://drive.google.com/file/d/1xtWOWTw4a6roG9Ke569dT6iNiIsX-8z6/view?usp=sharing
