I used a nail file and "removed" that slit from the spool and didn't have any more problems. Might be worth a try for you.
...or just turn the spool so that slit is in the bottom of the spool. FM quilting is a process that requires the correct tension, speed and the guiding of the fabric in sync with the needle asking that stitch. If you go too fast and that stitch is not complete your thread will break.....be it expensive or cheap........it has to be a smooth action between human and machine... Start out slow and work steady.....will not happen first time out.
