Time slider not showing time remaining

The time slider will get stuck, and not show the time in the episode or movies I’m watching. Example: I pause the movie at 15:30 seconds in, I’ll un-pause, continue watching and then go to pause it against 30 mins later and it still says 15:30. Confusing to remember where I left off if I need to stop it and try and watch it later. Any fix?

Thx
