2.5 maximum upload size

Hi, 

In the 2.5 assignment there is the usual maximum upload file size.  But the maximum is not what the course maximum file is set at.  It gives the Activity Upload Limit (10mb)  I've set in the moodle settings and also the courses settings a maximum upload limit of 200mb.  Is this a bug or is there a new setting that I can't find?

Thanks

Kieran
