Loading Template image

[Hitchhiker 42]

Hey y'all!
I've been working on getting vision as an off-season goal. I've got a small problem left right now. As you can see in the screenshots, my color-filtering and population-filters are working fine. Right now, though I've also implemented a shape-matching piece to get a report of all the matching particles. My problem right now is that the dashboard can't seem to load the template image to compare it.

I developed this with vision assistant and put it on the dashboard.
The small gray box at the bottom in the screenshots is supposed to display the template image, but it isn't showing anything, so I concluded that the template image isn't loading.

Is there a reason for this? How can I go about fixing it? Thanks!

EDIT: screenshots are in a post below.
