See, I don't agree with that. That sounds like marketing to me. You can fmq with any wt of thread you want, how would the bobbin thread tension be right with a 60 wt or a 30wt equally? Your bottom line thread is a fairly light weight thread. It may be that the case is letting it slip through too easily. Just like we need to adjust top tension for different weight threads, so does the bottom need to be.
Vertical is a little friendlier, but horizontal isn't impossible.
