STM32PackCreator: Why is optional Component Value "Subgroup" is needed

I want to create a new expansion pack. During adding the bundles and components I've got a problem to leave the "Subgroup" empty.

Using a dash "-" will be able to apply the component but it raises an validation error during "save and pack".

Editing an old expansion package ( I had made a few years ago) , the Subgroup is still optional.

What kind of "switch" makes the Subgroup as mandatory?
