Can't save game or see review tab

I made an endgame study, but when I put the PGN in an analysis board, there was no option to save the PGN at the bottom. There was also no game review tab. I tried with other PGNs and still got nothing.

Here's a picture:

Am I just missing something, or is this a bug?

Bruh its given there upgrade to save

LOL

But then where's the game review tab?

I checked, but none of the membership plans say anything about saving analyses.

  you can't open it because of this 
  your internet connection also must be lagging

Great then.

Game review is only for games from my experience. 

Oh, ok. Thanks! .

3…Nf6 was a game losing blunder. This is not an endgame study.

This is an endgame study:

There's a Game Review button. You have run a review to get the tab. If you want to save it, you could add it to a Library Collection. The other Save option is to save it to the Saved Analysis section of the site.

Yeah, that's one of the other PGN's I tried with.
