Tag Fields display

Hi, i have a small problem regarding how tag fields are displayed after saving, i know it's a simple answer but i'm clueless and would appreciate any help.

I'm using danos normal discogs.src, other than basic tag fields, i'm using publisher and catalog.
Publisher is pined to Label, and Catalog# to Catalog.
When script writes tags all tags fields are writen in mixed case, eg
Artist: xy

But when i for some reason can't access discogs server, and put those extra tags by hand, they look like this:

What is causing those fields to display in all_upper case, and how can i prevent-revert this from happening?


ps. i'm using dbpoweramp pop-up to view all tags in win explorer later on..
