Short description of error
Reflection plane has "show data" checked by default (only needed for debugging), which confuses user thinking it's broken, since other reflection probes don't even have this feature.
This might not technically be a "bug" but at best it's inconsistent. It took me lots of searching before I finally realized why it was happening. I suspect others will be confused too.
