Bug - Normal Squigly's ground combo problem

[Snowbee]

When I start a first combo of a game(without back dashing, charging or getting hitstun), then squigly's ground basic combo upgrade does not works for this whole combo.
Same issue is always in training room.

my phone is galaxy Note 9

I'm not totally sure I understand the bug report. What part of the combo is not working? Could you provide the exact steps required to reproduce this issue, and also explain what the expected result is?

Thanks!
