Battery Low UltrimSlim RGT problem

First of all it's a very good ROM by Ron.gt
But I have one problem,I'm using this ROM and whenever I charge my phone the led notification light does not change from red to green upon reaching 90% and battery always gets stuck at 99% no matter what.
I need to switched off my phone,plug the charger and then only the led notification light will change from red to green and the battery will be full
