Density & Stitch Width Settings Not Keeping

[Cyndi50]

Trying to update my density and stitch width top stitch settings and it won't keep the numbers that I input into the fields. For instance, it sometimes changes, I put 6 in Density and 3.3 in Stitch Width (mm) and it switches to 5 and 3.299. How can we get it keep the settings we input?
