I would not use the invisible in the bobbin. (JMO) I tried it once and it ended up a mess. I have used it on top with regular on bottom and that worked well. Think your top thread is too tight if bottom thread is showing thru top. Did you try to loosen tension a little? Maybe you are going too fast for the machine and that is why the thread is coming up. I would try those suggestions and maybe someone else with more experience will have better ideas.
Good luck!
