MATCHING MOMENTS

I am on the second bingo board. I didn't have any issue with Matching Moments until today. In Matching Moments game, I have 924 maple leaf coins built up. It states 900 coins to keep going and continuing the game. 

However, every time I click to use 900 of 924 of the coins I have; it does not let me do so. Yet, another glitch to deal with. Keeps directing me to the page of buy more coins!!!

I posted this and went back into the game........now it is stating I only have 724 coins!!!. I left showing 924 and now I only have 724. There is something major wrong with this game!!!!! It keeps taking your coins.

And.........what is up with this all of a sudden either one or two attempts to finish for an event?? Why can't it just be finish 20 or 30 games?
