I use to have the same issue. Then found out when I created the design in my software, I had a different hoop size selected that I needed. In other words, say I created a 100X100 design, but when I created it in my software I used the larger hoop size. The machine requires you to use the same hoop size as it was created with, even though it will fit in the 100x100 hoop. Hope this helps.
Sounds like the display is going bad.. it may need replacing. I they are very hard to find them and the dealer only wants you to buy a new machine. Sometimes you can find them on eBay. Good luck.

With the additional layers it will take a higher top thread tension so the take up lever pulls the extra top thread from bottom side through the fabric stack before it takes it from the spool.
If youre not sure whether top or bottom thread that is nesting, try a different color top thread to make determination easier.
