%%pt_single/plural%% vars for Custom Post Types

I am sorry for asking that again if already asked, just couldn’t find the proper search form for the plugin only…

Anyways, neither %%pt_single%% nor %%pt_plural%% for CPT made by Toolset work for me, it stays just like this in the Meta Description box, where I would like to have it.

Any help is greatly appreciated and sorry again if been already asked…
