Hi all. I am very new to machine embroidery, I will have a good run of stitching then my machine will prompt me to change the bobbin since it’s low. So, I wind a new bobbin, place it in, rethread the upper thread and then resume stitching from where it left off. When it begins back, it just stitches the white bobbin thread on top instead of the upper. It only does this when I change the bobbin and I don’t know what magically fixes it. I don’t change any settings during the bobbin switch, so nothing is making sense to me. Any help is appreciated! I have a brother PE900

Pls help before I throw this thing out the window. The bobbin thread is going down instead of the upper green thread. I’ve retreaded it and checked the bobbin. It starts green and then goes to the white bobbin. Pls help. I’ve been doing this for one week.
