Lomza area during Partitions of Poland - Polish or German, or Russian?

Question that has bothered me, both grandparents came from Lomza area , on
one Death record for one of the five girls they lost here in the states, it says
Russian Poland, then on another daughter, it says German Pole.

This was like 2 years after the first one, maybe a typo?

I guess it must be a typo - both phrases don't make a lot of sense.

Depends on the year they were born.
Poland was under Russian regime at one time, then it wasn't.
