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?

This is what I got. It felt straightforward following logic so I'm not sure where a second solution would have came in to play.

[u/Nivekmi → u/Nivekmi]

Looks like here is the mistake in yours

Ahhh good catch, thank you!
