Are you using the plastic one or is it metal?

I've used both and find the newer plastic ones don't leave as much of a mark. The key is not to push them in too firmly. It's only purpose is to hold the reed flat.



They're easier to remove when the reed has fully dried out. If I've pushed a reed in too tight I'll have to work it back and forth at the bottom to try to ease it out.

As long as you didn't pull up on the reed trying to get it out and fracture the reed the marks shouldn't hurt anything. Just put them in using light force in the future.
