You might have it setup wrong somehow...
Try this its right from my Calk 4.2 kitchen but I added Sense 2.5.2012 and a 28011 hybrid SYS. I know it works very well been my daily rom for sometime now. I try flashing newer ones but I always end up coming back to this. I included my erv file so just drop all the folders into the root of your kitchen and it should add everything where it needs to be. Then open the kitchen and choose the erv file.

Some of the sense tweaks are untested/might not work.
None of this is my work Ive just downloaded things myself but you can check out these links regularly to get updated SYS folders and such.

I wish I could remember where I downloaded the SYS and other misc stuff to give credit.
