My b2evolution Version: Not Entered

I had just set up my b2Evolution system on my site, and was testing the uploading files feature. I noticed that it would only let me set it to allow files less than 2048 bytes (2MB). I would like to be able to upload files up to 10MB in size, but it wouldn't let me set it that high.

I assumed my php settings were low, but it didn't look like they were. Here are my php settings: http://www.simmerssociety.net/phpinfo.php

If you look near the bottom of the table titled "PHP Core" you'll see my local value for "upload_max_filesize" is 10M. So why can't I set my b2Evolution to allow files higher than 2MB?
