Sturggling with jigsaw blocks

1.20.1 minecraft. I'm trying to get a jigsaw block to choose from several random simple structures to place inside of a larger structure. However, I can't seem to get the generate button in my jigsaw block to generate anything. My filepaths are data/overhaul/worldgen, then inside of worldgen there is template_pool/totems.json and structure/totems/totem_1.nbt. totems.json: { "fallback": "minecraft:empty", "elements": [ { "weight": 15, "element": { "element_type": "minecraft:single_pool_element", "projection": "rigid", "location": "overhaul:totems/totem_1", "processors": "minecraft:empty" } } ] } The bottom block of the structure totem_1.nbt is a jigsaw block pointing down with Target Pool: minecraft:empty Name: overhaul:totem Target Name: minecraft:empty Turns into: totemic:totem_base{Wood:"totemic:mangrove"} The turns into line is valid and works with /setblock. The jigsaw I am using to try and place it is filled as follows: Target pool: overhaul:totems Name: minecraft:empty Target Name: overhaul:totem Turns into: minecraft:dirt
