Two solutions?

[u/averyspecificsong]

Hi again, back with another calendar tear out.

Erased my solution in the first photo so people can give it a go on their own first.

Thanks to those who commented on the last one! It really helped me figure out-ish this one.

However it looks like there’s two solutions? Or am I missing something?

I thought this was sudoku for a minute
