Default Bug in Cyanogenexus ROM for Xolo Q800


I installed this ROM on my Xolo Q800.

I'm really liking this ROM & everything works expect for 1 thing.

If my phone is locked & I receive a call, the screen does not light up to show the call. I only hear the ringtone. When I unlock my cell, I have to access the call via the notifications bar!!!

I don't have a lockscreen set up for my phone.

Can someone please help why the call works this way? Is there some setting required for this?

Thanks a lot for your help in advance

Best Regards,
