The red dot case is the standard case that can be used for everything, including embroidery. If, and only if, bobbin thread is pulling up during embroidery then use the yellow dot case. Note that if your original case shipped with the machine was destroyed or damaged, there could also be damage to the hook race that the case sits in. If you hear clicking when sewing, or the bobbin seems to jump and rattle, there's a very good chance of burrs on the hook race. That usually leads to the new case being damaged as well.
