What's bizarre is that I've watched it display properly, then not, then properly, then not again for a couple of days now. Tried emailing ModularGrid but no response yet. I mean, it's no big deal, just a little irritating.

Cannot reproduce it and still have to check it.
Do you know about the Panel Selector mode? If you enable that top right there appear small arrows on the modules where you can select different panel versions.
To pin down the error: are you using that mode?
