I am having issues with wire types and sizes for a large hospital job.

For instance I have an 800A panel that I want to feed with parallel #600 and #2/0 E.G. To do this I created a wire material with the parallel #600 assigned to 800A ampacity and then assigned #2/0 ground to the 800A ampacity in ground conductor sizes, then I created a wire type called "Parallel 2" (b/c i have another wire type for parallel conductors with max size #500 kcmil) and assigned the aforementioned wire material w/ parallel #600's to the newly created Parallel 2 wire type.

I've used this method before with other wire types/sizes and it worked, but for some reason I'm getting crazy results when I assign this type to the circuit properties. For this particular 800A panel I get the following result for the wire size:

"3-#3 runs 3-#500, 1-#500, 1-#2/0, 1-#6 runs 3-#500, 1-#4/0, 1-#1/0"

I have no clue where this info is getting pulled from. Some wire types/sizes I've created work no problem, others I get results like this one.
