Saving PQ file as CSV - Software that I am uploading it to says it sees values in my blank rows?

I feel like this is either a simple solution or a complicated one, but I've been looking at it for too long that my brain feels fried.

I basically have a file that I've manipulated in PQ. Say it has a header and two rows after the header of data. When I go to upload it into my accounting software, everything uploads fine, but the software thinks there are values in row 4 up to row 7.

Is there something that I can do in PQ to clear out all of the rows that aren't being used or is there something else I have to do outside of PQ?
