That was due to the "global config" still being included from the global macros. That is not necessary anymore, as everyone should use the project-specific config. Otherwise, the variables will just not be set, which would lead to some "unspecified" behavior (default would be 0 = %false(), don't know what happens with the color for the tagged values). Therefore, there should also be a check implemented to at least warn you somehow (on diagram or during pumla update) about the fact that the current repo should be "setup right" with "pumla setupprj".

Maybe I can check one of the variables for its default value (color = 0) and then include the global config? have to check that, reminder for me.
