Ok... I know what is going on.
My Curse of Strahd theme does not really use graphic icons like most other rulesets.
It is designed to use a short wide button with dynamically created text on top.
You will want to remove: data_library_com.lua
or adjust the following line: DesktopManager.setDockIconSizeAndSpacing(100, 24, 0, 6);
to something like: DesktopManager.setDockIconSizeAndSpacing(100, 90, 0, 6);
and play with some of the other settings.
