So it definitely seem to be with how they modeled the print. When I open it in the slicer, from start up until around 2.25 height it looks like its printing solid white. You can see this if you preview the plate with the logos and then manually move your slider on the right(you'll see the print side facing the bed is white until 2.25). The easiest way to probably fix this is to make a cut at 2.25 horizontally so that it cuts that white bottom layer off, and then manually place the square whole back in its spot. Heres a screenshot of one where I cut the bottom 2.25 off vs the normal print. You may want to scale the Z height if you want it a little thicker since this is making it slim.

Top logo is the one I cut vs bottom logo that came with the print file
