Monofin imprint????

[Mermaid Saphira]

I just got my new tail about a week ago, but when I went swimming in it for the first time my tail made a silver imprint of my monofins structure onto the dark blue fabric!!! Any tips on how to fix this or why it happened??? Thanx <3
PS: I'll upload pics later...

I think I may have seen something like that but can't be sure. Pics would help!
