Published values get lost after an N number of them

I tried looking for some published value from a Background node called "Green". Before this, I did publish several more values from other nodes, but I only see a handful of published values when I try to look for the RGB values and connect them to my "Green" node. I'm not sure if this behavior is unintended, but I'm confused on why I cannot find the values published by my "Green" node.

I also tried to turn the RGB values into expressions and connect them to the "Green" node, but they don't connect correctly. It's as if there's an error with the node since it turns red.

Hopefully someone can help me figure out what the issue is or maybe it's just Fusion being buggy. (I've also tried restarting DR and it didn't work)
