Something is very wrong with bowling

Several times now the end score was different than the game I played. For example, I just finished with a all strikes and a 9 at the end, it should look like X X X X 9, but my end score was shown as X X X / / for 50 points, and the bot I played with got X X / / / for 75 points. This makes no sense! Another time the bot had 9 on the second round ( so 0 9) but ended with a score of 69 with an 0 9 X X X. That's not even possible! This has just started happening in the last month or so.
