Default Messier Catalog and Its Contents?

Apart from software programs that use "the" Messier catalog, where is the
official version and the description of its fields?

I don't think there is such a thing as an "official" version of this
catalog. It isn't really used professionally, and it isn't maintained in
the way working catalogs are. By reference, it has been incorporated
into many catalogs. You can find the original in various versions online
(in English, see http://seds.org/MESSIER/xtra/history/m-cat71.html). As
you'll note, there are no fields in the modern sense, just a list with
commentary and coordinates.

I suspect not. My question came about as a strange result I got out of TS6
(Bisque). They seemed to be confused over calling the objects M10 or just
10. They dropped the M. A very odd way to do it.

This site has some background:

and a link to the original 1781 version:
