I've never been fantastic at charts, but something odd is happening today that I've never seen before. Below is a nerdy thing I'm doing for my D&D group...

Original chart

I don't want to fill the post with images, so - see on the left, there's the big brown segment with the 15000 in it? I'm trying to turn that red via Edit, Format Data Series > Area, selecting a red color + Ok. And that happens, but the ice-blue segment in the same bar changes colors at the same time and I don't see why.

The ice-blue is the segment I changed just before this one, but it isn't selected anymore so I'm not sure why it keeps getting tweaked. Any ideas?

Linux Fedora 44, KDE Plasma 6.6.5, Calc version 26.2.3.2 (X86_64), the file is .ods and I'll try to attach it. Please advise if you need anything else. TIA!

While marking a student's unit exam, I just wrote

"...methane molecules are symmetrical, meaning their charge distribution is also symmetric, and that's another reason it's nonpolar."

I wrote that on autopilot, it felt okay to me at the time, but I don't have the foggiest notion what rules there are, if any, for choosing between 'symmetrical' vs 'symmetric'. Please teach me?
