Jigsaw Block not working in generating custom structure

Hey y'all, I'm having some issues with a structure generating. It's a tower that's taller than 48 blocks so I needed to split it into 2 structure files (bottom half generates first then uses a Jigsaw to generate top half). This one is especially stumping me because 1. I'm pretty sure I did everything right, and 2. I basically copied the files from another one of my structures (which does work) and just changed the structure names. Does anyone know what I'm doing wrong? If more info is needed lmk 1st image is bottom half Jigsaw, 2nd is top half Here are the structure files (2 of them), structure.json, structure_set.json, and template_pool.json files (2 of them), respectively
