That's messed up. I hesitate to say this but it looks like Apple doesn't know how many Polish language code-checkers it takes to make sure an iOS release is ready.
Worse thing: it is a result of a bug rather, not the new font. Day-label is not properly positioned on iPhone. On iPad is OK. See image. BTW: I send a note to Apple.

It has happened in the past with one of the updates, I think iOS 7.0 or something like that. A minor visual glitch that they will likely address in an update.
