I am using the default settings where normal to uncommon is 0.1 which is supposed to be the same as normal, but on an Assembling machine with 16% quality the chance for normal to uncommon is 1.6% which is only a tenth of what its supposed to be.

Ah, looks like they changed around the way next_probability works, I updated the default settings and changed the tooltips to accurately describe the way it works now. You might need to manually go into mod settings and reset them to the new default after downloading 1.1.1
