Shed STILL on mouth after weeks? Please help!

[Blizzard]

Okay, so my boy Sam has a problem that I'm not sure if I should worry about or not. He shed on October 9th. It wasn't a really bad shed, it was pretty clean after a small soak except I noticed he didn't get the shed off of the front of the snoot//mouth. (there is also some super small shed pieces on one side of his heat vents, making them look odd-ish) The next day I sprayed that area lightly and repeatedly with a mist bottle and gently peeled some shed off, but when I got the the front of his snoot he would NOT hold still and was getting stressed, so I decided to cease fire and settled with thinking he would get the rest off himself. Well, it's November 6th now and it's still there. It doesn't seem to bother him at all, he acts completely normal and happy like always, is eating wonderfully, but it bothers ME because I'm not sure if I should be worried.

Should I leave it and see if it comes off with his next shed? Should I try to spray it again and peel? I this normal? Is it bad? I could really use some advice on this! Thank you SO much.

*note, his temps and humidity and everything are ideal so I really don't know how this happened?

Here are some pics. They aren't very good as he was being really curious today and wouldn't hold still, but I hope you can kind of see what I'm talking about.
