As of right now, to my knowledge, there aren't any placeholders that would display the prefix or display name of the highest weight group user is in, there's only %luckperms_highest_group_by_weight%.

The reason, why I am asking for this, is because when for an example main track contains default and expands to donator ranks when I try to display staff ranks as the primary with current placeholders being offered it often switches showing donator ranks.

So, if you could please make something like %luckperms_highest_prefix_by_weight% and %luckperms_highest_group_displayname_by_weight% I'd be more than happy.

%luckperms_highest_group_by_weight% returns the display name.

%luckperms_highest_prefix_by_weight% would be the same as %luckperms_prefix% or %luckperms_prefix_element_highest%

Only other thing is: make sure you're using the latest version of the expansion.
