I NEED HELP!!!

i just bought some 6/0 flat waxed thread from bass pro shops, its Dansville brand. i tried it and got super mad cuz it kept fraying where it would come out of the bobbin tube, so i declared that the thread SUCKED! later upon closer inspection, i saw a small nick in the tube, the main culprit.

now...HOW DO I REMOVE THIS PROBLEM!?!?!?

thanks
