The HStack is meant to be column headers for the list items and need the same styling This seam to be a short fall of lists in the dark mode.

I tried to put the HStack is a List but this does not look good because the other list has a ForEach where the whole background in Dark Mode goes black but the HStack leaves the outer background its List white. Why does not ever area in dark mode black for all elements is a list here either. Dark Mode should make all background Black. Non of the Pad OS should be white.

I actually found a rogue line I had added which caused what happened and it was not the sort. It did take some very detailed debugging to find. Sort is off the hook this time. After 50 some years of coding I can still create bugs requiring very detailed debugging. Still have a few features to get working but it runs on my iPar Air and my Mac Pro and looks good so far.
