Thats pretty weird, If you didn't when you load up the old save make sure to quit out of the game completely first and maybe run whatever temporary file cleaner you use just in case any data carry's over between the saves (no idea how or why but it can happen).

Theres a mod [http://www.nexusmods.com/skyrim/mods/28668/? here] that works like an app to let you edit out quests from your save, i've never used it and can't vouch for it though so make sure to read all the comments and instructions if you try it.
