Have you checked the nut action?

fret between the 2nd and 3rd fret on each string, and look at the gap between the bottom of the string and the 1st fret. There should be such a small gap that you should have to tap on the string and listen for the impact with the fret to tell that there even is a gap.

Sweetwater may have done a setup, but may not have adjusted the nut action low enough if at all.

A high nut action will cause the guitar to pull out of tune much more in first position chords. It may not resolve the issue entirely if you play with acoustic "kung fu grip' hands, but it will help.

Also heavier gauge strings and adjusting your playing style will help.
