Hi Long, thank you for the reply. I'm not so sure it is an Elementor issue, I will post on there as well to double check. However, as you know, Custom Post Types in WP operate the same as standard WP Post types (or at least, they are supposed to).
Within Elementor, when you are creating a template (page/post/pop-up etc) that uses dynamic data, you can click the Preview Icon and select Settings. Then you are given options of 'Previewing Dynamic Content as' and choices of Archive, with several options; Recent Posts, Date Archive, Author etc) and then Single, with options; Page, Post, Landing Page etc.
The issue I am having is that the CPT created by Metabox isn't an option in this list, nor is it available in the Templates Conditions options i.e selecting Singular - Sponsors (Post Type) I can pull the data through using a combination of TP Custom Fields and Post Title (not all the widgets will access the meta box correctly. The Image widget and Text Editor Widget for instance won't fetch the CPT Logo image or WYSIWYG field respectively, but using TP Custom Field will)
Having read a few Forum Posts on Elementor, I'm of the mind my CPT should be available to access through both Preview Settings and Template Conditions.
