Appearing Transform Group

[criticalone]

HI,
In some middle of my making of the rigg, when I parent some joints hierarchy for example to: l_ik_elbow_anim a new group under parent is appearing called transform and inside this group (transform group) is my joint hierarchy wich i parent. When i try unparent joint hierarchy from transform group and parent directly to l_ik_elbow_anim, new transfer group is appearing under parent again and my joints are in this new group...and again and again and again!...
Is completely unnecessary form my rigg point of view, How I can solve it? I don't need this TRANSFORM group.
Any idea ?
Thanks:)

ok, i found that happens when parent have different scale than 1. After freezing transform (just scale) i'm able to delete transform node and parent joint hierarchy directly where i want.

Pozdro:) heh
