Hmm. I just tried setting the expression to $area and using the 'Formatted
numbers' option for the layer: worked. I also used just an expression:

 format_number( $area, 3)


and that worked too, even where the area result was a whole integer, i.e.
label was 12.000. I tested with precision of '1' and both worked fine. Can
you share the data, even if it is just a file containing the individual
feature that is not labeling properly?

New documentation for labeling canvas map tools is forthcoming. For now,
you can reference:
