Can someone please help me figure this out?

I'm new to houdini, only done some fundamentals courses and this motion design course, and completely stuck on this and not getting replies for long periods from the course I'm taking so can't finish this last week so I can move onto my next course /sigh.....

Anyways, I rendered out my shots we made with all the AOVs in the karma render settings and a wrangle creating a bunch of primvars. I've gone over the videos again and again for my course and I can't see anything different, and all looks correct, but when I get to the compositing videos for it in Nuke, the PuzzleMatte AOV is showing the alpha reversed for some reason, and has some weird anomalies in it, and all my other pieces like leather, metallic etc. to split up the pieces of this headphones animation we created, all show there is something wrong with the AOVs as they are either blank, or show the leather and metallic materials all mixed together.

When I go back into houdini to look, I can't find how that's even possible. Especially when it did the color just fine and the AOVs just targeted each individual piece that the materials were linked to.

I don't know what else to do to troubleshoot or where the issue is, so that I can move on. And already 3 weeks behind =/

Any help would be greatly appreciated so I can finish this course and move on to the next.

I also tried sample frames from my other two shot set ups and they aren't exporting any of the custom AOVs at all, so I'm completely stumped if there is supposed to be a different way than the way it is set up or somehow I have it set up wrong and just not seeing where the issue is. My shot 2 branch in stage might be different than the other two because I was trying different things to see if it would work.

I got the shot 3 to work, which was the first line I set up......for some reason had to just rebuild the karma render settings with the exact same settings, minus I noticed primarysamples aov I accidentally had on float and not int, but that wasn't the issue. But manually rebuidling that got the AOVs working on shot3, but show 1 and 2 still do not work at all and I can't figure it out.
