Raidpet unit frames when set to growth direction "Down" and column growth direction "Right", the raidpet frames grow in both directions.

Example: In winter grasp is easily notice as people obtain vehicles, instead of the expected behavior of being anchored and growing more columns to the right, the anchor appears to be in the middle and new columns of pets appear on both left and right sides as the numbers grow.

I have this exact same problem in raid with my growth direction set to left

This is a problem with the raidpet template. It's code is made by blizzard and is protected against changes. I already looked into changing it in some other way but was not successful. Thus multi column raidpets remain kinda broken at the moment.
