List:

I have an item in a project, name a message structure (LMXXXXXX).

This item is in a BOLD font v. typically they are in a regular font.

Curious why the difference or what this bold formatting indicates as well as the
cause.

This means "Does not exist": somebody must have deleted it from the
system...
