Sometime XUB works perfect with Xperls raid frames, and others it needs a little kick.
Here the kick you should deliver....

Use /fstack to identify the name of your frames

open XUB, click Unit Frames, and set up Custom Raid Frames
for raid# enter: XPerl_Raid_Grp@UnitButton#
Save and you are all set.
If you use the frames horizontal like I do you may want to make use of the carriage return with a couple groups so you can get 2 lines of buttons.

something like this....

• Groups
  
  gTank1,SB_RighteousDefense,*
  gTank1,SB_HandofProtection,*
  gTank1,SB_HandofSalvation,*
  
  gTank2,SB_LayonHands,*
  gTank2,SB_FlashHeal,*
  gTank2,SB_HolyLight,*
  
  
• Profiles
  
  n,raid,gTank1
  n,raid,CR
  n,raid,gTank2
