Miter saw issue - left side bevel detents off by 0.4°

Bought the Flex miter saw, and am using a digital angle finder to check accuracy of the bevel stops.

Readings:

Right 45: 45.0° (after adjusting the 45 screw) Right 33.9: 33.9° Right 22.5: 22.5° Left 22.5: 22.9° (+0.4°) Left 33.9: 34.3° (+0.4°) Left 45: 45.0°

So the right detents are basically perfect, but the left 22.5 and 33.9 are consistently 0.4° off. 0° is dead on. The 45s can be tweaked with their screws, but the 22.5 and 33.9 detents don’t seem adjustable at all?

Anyone else with this saw seeing the same thing? No way to adjust the 22.5 and 33.9 right?
