MySQL privilages revert back after changing in phpMyAdmin.

I am having troubles with MySQL privilages, using phpMyAdmin and Cpanal. Does anyone have any idea why I alter MySQL privlages in phpMyAdmin, and 4 hours later they revert back to the original settings?

I think it has something to do with conflicting server configuration. Something is telling MySQL to have one set of privilages on a server level, such that my changes in phpMyAdmin are only temporary.

This is not really a progamming question, as its more of a hosting issue since its about server conguration, not really PHP or code. I'm hoping some of you hosts would have an idea on why this would be happening.
