My Avatar Style & beard lens is getting rejected because of 'copyright issues'?

Hello! I created a beard lens with avatar style component. I create the beard image myself on Photoshop.
Reason of the rejection:
This Lens contains unlicensed, copyright-protected content owned by Snap Inc. Content in Lenses may only feature original or authorized works

Avatar style is an existing component in Lens Studio, so I believe creators are allowed to make lenses with Avatar style. If it is going to be a copyright problem in the end on the publishing step, then why Avatar Style feature is available in Lens Studio?
Do you know a solution to solve this problem? Thank you so much.
