I updated my container from three to four columns, and added a fourth stylized text to display @item.value.message. The data is there in the data source, but the value does not appear. In fact I don't think the column is appearing. If I change it to static text I still get no output.
The column is not hidden. The column is a Span like all the others.
I also added a fourth static column header in a separate container up above, also updating it to 4 columns, and it doesn't appear either.
If I drag the column up to index 3, that it, make it the third column, I still get no output.
Both columns - the new "Message" header and the Message column - show up OK in UI Builder. But when I preview the page it does not show my updates.
What can I check next?
