The titles of songs have been changed

I switched from a Samsung to a Moto phone. All of my MSC music was loaded onto my Moto. However, the titles have changed. On many of them, the track number is now displayed before the title. When I had originally loaded them onto my phone, I had removed all the track numbers to create a purely alphabetical list of tunes. When I try to change the title in Tag Editor, I don't see the track number in front of the title. It is in the Track box, but even after erasing it from there, it still appears before the title. I have even gone to the Albums tab, located the tunes there and erased the track numbers from there, but that did not work either. Erasing the title and retyping it in the Title box did not work either. What can I do to permanently delete track numbers and get back my alphabetical listing of titles?
