Cosmetic Threads Bug

Hello All,

I've encountered something that I consider a bug in the cosmetic threads feature and would like to know if someone has a walkaround for it or a fix for it.

When selecting an edge for cosmetic thread everything works fine only that another face is also showing the shaded threads. It's mostly an annoyence but my Solidworks teacher in uni did not have the answer

Thank you.
