Unable to submit my puzzles despite having the correct solution.

[cathymath]

I've just completed these two puzzles (IDs #147939652 and #147943147), and despite having the correct answers (and using the button to check if my answers were correct), I was unable to submit them for marking. The answer grids also did not have any information despite having filled all the parameters out. Attached are screenshots of both completed puzzles, any insight on what happened? Thanks.
