It is def a pesky little thing.
I am trying a few things, I sent you my latest beta bundle, feel free to let me know if you have any issues with it, as that is the codebase I am working off.
It should fix some of these things. I added a todo list to fall back on overrides e.g. Tag1,Pencil,NoColor would just render Tag1,Pencil, <Color if default is used, True or false default used, otherwise, no color applied>.
This is great learning process for me!
