If the adjustment of both brake assemblies are good and you can notice that the one side of the brakes are pulling harder than the other that would lead me to believe that the problem is the grounds of the brake assemblies on the right side of the trailer. A lot of times trailer brakes ground to the frame. I would just run all of the grounds back to the main ground harness of the trailer to see if that fixes the problem.

The other problem is that it could be that your brake magnets are bad. Although it is a new trailer it's not impossible to think that the magnets could be bad. I attached a help article that details how to test the magnets.

Normally with a new trailer brakes the problem you described is assemblies that aren't properly adjusted. If they are Nev-R-Adjust brakes typically just applying the brakes several times will get everything working properly again.

Check out the video I attached at the 4:25 mark to see how to initially adjust assemblies.
