Page Template Shortcode not working

I have tried using

[wpdm_package id="32439" page_template="page-template-1col-ex-audio"]

and various other templates in the shortcode and they load link templates. I am trying to use these shortcodes in various places on my website outside package pages and they dont work. Link templates work perfectly. For example i can load a link template using

[wpdm_package id='32439' template="default_template"]

on a woocommerce product page just fine. However page templates do not work. Can someone look into this
