ZiKZ 605-R Bumper customize issue (PTS 13.12)

The "Stock" bumper is as default at the ZiKZ 605-R:

But if I buy the "Winch Pipe", the "Stock" will be blocked and I must reach level 13 to get this bumper unlocked:

I think, the "Stock" bumper must be level-free.

Hello! Thank you for the report, the team will take that into account.
