'Progress' steam achievements only update on steam after closing the game. Normal behaviour?

I have a progress achievement set up, however when I’m in the game and press L a few times the achievements in the overlay doesn’t update to reflect my progress. Only after exiting the game do I see the progress bar updated. Is this normal? it’s not ideal when it comes to player feedback.

Also how can I get the progress milestones popup? Like when it says 10/20 for the achievement. Thanks.
