"Roundabout" and "Normal" were two segment "types" that Waze quoted to us when we were discussing the failure of the mass unlock to actually unlock everything. There was, apparently, another type which was missed in the original mass unlock, so they ran it again, within the last couple of weeks. It may be a leap to suggest that this unlock also had another unintended consequence for some roundabouts, perhaps if they were the other type, which Waze stated, "was old and we don't know what it is for," they got un-roundabouted?
That's really a stretch, but is the only correlation I could come up with with recent activity/database updates that you wouldn't see in the GUI.

That certainly doesn't look like a real roundabout.

What is a center node? Never saw one
You could only see them in Cartouche, so I do not believe this is the case, here. There is a node, invisible in WME, at the center of a roundabout which actually defines the center and the roundabout object itself. If it gets deleted, then the roads cease to be a roundabout, and they go back to normal segments.
Pretty sure Waze rarely, if ever anymore, will do geometry adjustments based on drives. That made sense long ago when there were not very many editors, but today there are enough editors that that type of process is no longer necessary.
