polygonsOverlap and .overlaps not working?

I’m trying to move the position of a rectangle when it overlaps with another rectangle. I’m doing the most basic rendition of it right now but I just can’t get the overlap methods to work - I’ve tried both visual.helpers.polygonsOverlap and .overlaps() and they both return False even when the rectangles are overlapping or even right on top of each other. However, it works as expected when I have a triangle overlapping a rectangle.

OS (e.g. Win10): Windows 10
PsychoPy version (e.g. 1.84.x): 2020.2.10

Thanks in advance and apologies if I missed something obvious, I’m relatively new to PsychoPy.

Here is the code I wrote in the code snippet.

print(visual.helpers.polygonsOverlap(target1, target2))

if (triangle.overlaps(target1)):
    triangle.pos += (0.2,0.2)

if (target2.overlaps(target1)):
    target2.pos += (0.2,0.2)

This is the full code, since it’s compiled from Builder it’s quite long
