Game ver: 0.18.21 (though I've experienced this on other versions)

I'm just trying to determine if this is a bug (less likely) or I'm doing something wrong (more likely). My percentages remaining vary widely and often show >100%.

Here's a screenshot (https://imgur.com/a/1hDPiOZ) you can see at the bottom Stone #0 has 1086% remaining, and there are others with >100%.

Is this an issue with my settings somehow? I am playing with Krastorio 2, but no other mods that should be affecting resources.

If they're infinite resources it's normal, otherwise something screwy is going on.

I think the richness is turned up a bit, but no, they're not infinite. Any idea on what I can check to fix it?
