Hawkeye input bug?

I can’t do C>hcf.C to get arrow canceled into piercing if I hold away while I hit C then do the hcf. The inputs look like this: 4C1236C. If I start the hcf right after C (C41236C) it works just fine, but the issue is mainly when I dash back then C>hcf. So far this is the only time I’ve seen a normal that can be canceled with a qcf and not a hcf in this manner.
