Squiggly bobbin thread Aurifil 50 wt

I recently wound four bobbins using my bobbin Winder of aurifil 50 weight cotton Mako thread. The bobbin seem tight and fine. I did not notice any issues. This is my first time using this type of thread in a long arm. I noticed that when I went to test the tension as I pulled the thread clockwise out of the bobbin and tested the tension and then release the thread it was squiggly. I've never seen that before. I thought maybe the tension on the bobbin Winder was too tight since the 50 weight is a little thinner than the 40 weight Glide I normally use. Is this a possibility? How would I know what the preset tension on the bobbin Winder was before I try to make an adjustment?
