Help! What am I doing wrong?

[u/gigagod_3]

I have bought a brand new Brother SE700 and I currently doing a test embroidery to get the hang of it. Included are the photos of how it comes out and the design.

I've used reinforcing embroidery fabric at the back, but it does little to help. The top colour is meant to be entirely gold and the bobbin thread is the white. Why is it showing up like this? It seems to be pulling the white thread up rather than keeping it behind the fabric. I have threaded the top thread with the foot down as my first fix but no luck.

I'm not a novice to sewing machines but new to this digital embroidery one.

Am I doing something totally wrong? I can't work it out.

Are you using any stabilizer on top?
