Z-Wave graph not showing repeaters as blue circles

I have several line-powered Z-Wave devices that are repeaters, and until maybe a couple months ago, they showed up correctly as blue circles in the graph. Now everything is a gray circle except for the hub, which is red. I am not using ZWaveJS. Has anyone else noticed this?

Look here:

In that thread, they were using ZWaveJS and the solution was to revert back to legacy. I am already using legacy (I've never used ZWaveJS)...

Yes, but the point is the graph hasn't been working properly regardless of JS or not.
