I tried to sign on to an existing site that I had created a username and password for previously, but LastPass didn't recognize it. When I attempted to sign in to this site it also did not recognize it. I then changed my password to the site and logged in. When the popup appeared from LastPass, it was asking me to add the new sign-in info to a completely different existing site instead of the one that I just signed in to. Did any of you ever experience this problem?
