Arms of the rig bends the wrong way?!

[MeteorxBG]

I have been trying to get into Blender Animating but this problem(at least i think it is?!) keeps me
from getting into this.
So the problem is that after i get the rig ready with all the IK constraints for both the legs and arms, arms give me a certain dificulty with how they behave(Luckily no problem with legs tho).

If i grab the IK target bone for the arms and push it up it just bends towards outside instead of elbow going backwards.note : Pole bone is already selected and is the one behind it.

this is how it looks like ;

This is when i push the IK Target bone upwards.

Now for sure idk much about this and this may just be how it should behave but since i have seen nothing on this THING, i had no other choice.

Select the bone with the IK constraint (so the ones colored in yellow), go to the bone properties, scroll down til you see Inverse Kinematics and make sure the Z axis is locked. This is a problem with how the blender importer auto generates IK so it is recommended for you to make them yourself.

For anyone wanting to have proper bending in the arms, I use these settings:
