Animations from Blender to Unity

Hi! I made an animation in Blender with armatures. When it is exported to unity it seems to be exported in multiple separated armatures when it is all condensed in one action in Blender. The shown names in unity are:

**Amature|HI

Amature.001|HI

Amature.002|HI

Amature.003|HI**

while in blender the one action is just called HI.

Why are they separated and how can i combine them?
Thanks in advance!

did you use rigify to unity tool?

Never mind, Since i have not been animating in a while i simply forgot to connect all of the armatures, Sorry!
