CVS Import 'limit' working too well

Hey people

I have a 'nonprofits' table I'd like to fill with data. My 'free plan' record count states my limit is '10,000 records' In all my tables I have under 150 records for testing purposes but I'm unable to upload a CVS file with 9430 records - 9580 records total - less than the 10,000 limit.

Not sure what's going on here. I'd welcome some help while I'm still in the website development phase.

Thanks
