Assignment

Hi guys!!!

When some student view the feedback given by the Teacher in the Assignment (On line Text), his grade is showed in the following way: Grade: /100. The teacher already assigned the grade, so it should appear in this way: Grade: 75/100. Attached to this message there is an image of what happen.

I've made a backup of the course and installed it inside another moodle installation with the same version and it worked right. What leads me to think that the problem is in the Data Base. But where is it?

Somebody experienced that and knows how to fix it?
Obs.: I'm using Moodle 1.9+

Best Regards
