Godox/Flashpoint flash is dark when using wireless trigger


I have an R2 Pro Mark II transmitter, a tt350 flash, and Fuji X-h1. When i use the flash at it’s least powerful setting(?) mounted on the camera (1/16) at 1/2000, f/4.5, and iso 100 it works fine/exposes correctly. As soon as i pull it off and use the r2 transmitter, while keeping it at 1/16 all pictures I take are dark/underexposed. Here are a couple pictures of the flash settings and example of darker photos: https://imgur.com/a/AzJd5Qj
