Add Custom Meta Data to the single store page

Hi,
I successfully added Custom Meta Data to the Store Locations ($listing_template and $info_window_template) but I don’t know how to add the same Custom Meta Data to be shown on individual store pages (below the google map).
I tried with wpsl_cpt_info_window_meta_fields and wpsl_cpt_info_window_template but obviously I’m doing something wrong – added custom field is on the individual store page not displayed.
Are this two filters the right way to do this?
Thanks for help,
best regards
Mario
