Maybe I'm not communicating clearly, sorry.

I checked my styles count before upgrading and then again after upgrading and the difference in the before and after does not make sense unless 1) I didn't get all the new styles or 2) some of my existing styles got deleted by the installer or 3) some of the new styles were duplicates of what I already had.

Regardless of whether I have all the styles you make or not it seems that the increase should be the number of new styles in 2019!
