I was not able to record a video but I hope the following provides enough information about what I wish to share. The following is a image of Air Walker not being able to reach sp3 with certain hits.

And even after another combo, there is no gain in power.

This was in arena so I didn’t mind pushing no to sp3 too. I actually fired my sp2 to see this.

What is wrong here. Can anyone give me insight? He does not reach so3 at all, but if I fire a sp2, he has over a bar of power.
Edit: I’m sorry if you wonder why the combo is 6 when I use sp2, I just got hit before firing the special, please don’t confuse.
