That is definitive. A side can only be one grit level. My 800/1000 stones are not split labeled like that, but the fact yours are indicates a possible wider problem. Maybe some are split labeled and some are just labeled wrong.

I'm OK with just using my 800/1000 stones in reverse order -- provided it's only a labeling issue. But if it's a QC issue and the 1000-labeled stone is really not 800 grit but something else, then that requires different action.

My 800 / 1000 paddles are white and gray in color.

Just received my 800/1000 stones and the 1000 definately feels more coarse.
I only have a jeweler's loupes to visually compare.
It seems to confirm it.

Should I just ignore this?

I can't check the magnification of the grit, but it feels and sharpens like the stone is labeled in reverse.

I guess I will just ignore the label.

It has me confused also.

I now have six sets of stones and these are the only ones that "feel" the reverse of what they are labeled.
I might buy some more so I can sleep at night.

I spent some time yesterday conducting various tests, to see if I could find a good way to tell the difference between the two stones. I'll spare the details, but while it's possible that the stones may be switched in some cases, the short answer is, I think the stones are so close together that it's hard to tell them apart. Add to that, if a new 1000 stone has a few errant diamonds that are larger, it could give the impression that it's rougher than the 800. Broken in, they seem a bit different, but they're still pretty close.

Obviously, if you're getting finer results from the 800, then use them in reverse. I'd pay attention to the results,,, over time it may change as the stones wear in.

As a suggestion, I wonder if a bit finer stone, like a 1200, is available? This might show a better progression, especially if the 1200/1600 ceramics aren't available. Maybe the 1000 is a little to close to the 800? Just a thought.
