Duplicated signature problem

I Created a new signature copy and pasted from html, I notice a slight mistake and re did the signature and renamed it but now it shows both signatures when I try to write an email , how do I fix this?
Also when replying to an email the old email text wraps around my signature and I have to hit return multiple time to drop it below, is there a way to fix this also?
Thanks in advance

It may be a corrupted signature file.

If you want me take a look you can send me the file. Close eM Client and copy C:\Users[username]\AppData\Roaming\eM Client\snippets.dat to another location. You may have to enable hidden items in Explorer to do that.

Then restart eM Client and email the copy to me at gary.curtin@gmail.com
