There seems to be some discrepancy between how MC33.0.20 is interpreting/using the attached code under Win11 and Mac Sequoia.

The attached images show that on my Win11 PC only the [Name] line is using a Bold Fontface but on the Mac Mini all the lines seem to be using either a Bold Fontface or a different font size.
P.S. Semi-Colon delimited lists are being displayed without the space between the semi-colon ; and the next entry in the list
