iTunes Syncing Ringtones, And Deleted Ringtones

Okay let me see if I can explain this easily enough…
I used a ringtone app to create some ringtones. They synced in my iTunes, but I eventually deleted the 5 from iTunes and converted some new ones. I now synced 15 new ringtones into my phone, but for some reason, I have the 15, plus the 5 I deleted at one point. I don’t understand how the ringtones are still in my settings “sounds”, when they are not in my “tones” folder in iTunes. I really don’t want to restore my phone because of some stupid ringtones. But how can I delete them in my phone? I’ve tried not syncing the ringtones. The only thing that did is not add the 15 new ones, where the 5 original are still somehow there. I don’t get why they are in my phone. HOW CAN I GET RID OF THEM??? Thank you!
