Problem: The user would like to display some user meta data that is managed by the Memberpress plugin.
Solution: Toolset functions and shortcodes will only allow you to display fields that are managed by Toolset: - https://toolset.com/documentation/customizing-sites-using-php/functions/ - https://toolset.com/documentation/user-guides/views/views-shortcodes/
According to this article, Memberpress has its own shortcodes to display user meta[mepr-account-info] https://docs.memberpress.com/article/112-available-shortcodes
You may want to create your custom shortcode to display the user meta, like this answer on StackOverflow https://wordpress.stackexchange.com/a/82335 Or this one https://www.cozmoslabs.com/docs/profile-builder-2/developers-knowledge-base/shortcodes/display-user-meta/
Or using a 3rd party plugin such as https://wordpress.org/plugins/user-meta-shortcodes/
