Hey ! @Tess I'm having a similar issue––my queries all look good, and in the right sidebar it looks as though the table should be displaying data.
However the table isn't rendering. It randomly rendered in edit mode but I couldn't reproduce it.
I tried your tip, changing the sort (which I haven't messed with until I saw this post-–all was working fine before with the sort I chose) and some sorts seem to show the table data again but the one I want doesn't.
