Prosites Upload Quota Issues

- My default WP upload setting within Settings>Network Settings is checked and set to max 1,000MB
- My 3 different levels are set for a max of 1Gig, 2 Gig, 3 Gig.
- My main site is set permanently to the highest ProSites account which is 3Gig max upload quota.
- My main site has less than 15KB currently stored within media

I am having an issue when I go to upload a photo of 85KB to the media folder of my primary site and I receive a "Upload Limit Exceeded - Sorry, you have used all of your storage quota of 1000 MB."

I DO NOT HAVE THIS ISSUE ON MY OTHER SUBSITES. ONLY ON MY MAIN SITE. I cannot figure out why I am having this issue. Please assist.
