I have various CPT setup. The issue in question is found on various posts created. For this excersize we will be looking a the Supply Chain Doc CPT and more specifically the post category " Supplier Database Verification " which loads one post called "GM Supplier Verification Form 2021". I am experiencing a issue where the "download" button is not loading the PDF file but rather the actual category again.
This is for your 3rd conditional to view a document but you have the [wpv-post-url] set as the link to view. Is it a case here you want to view the post or a document attached to the post.
As you can see the link below archive is working perfectly fine. hidden link
The download links are going to the PDF files that are attached.
I do notice that on some of your posts that you have an additional download field that was not created using types called document. Here is an example. hidden link
This post has no value in the upload field but it has the default wordpress custom field.
In such a case you will need to check if our types field is empty and decide what you want to display. Here is an example
Please note the use of [wpv-post-field name='document'] shortcode to get values of custom fields that were not created with Types.
I would suggest that you go through and make these changes to ensure that you're covering the various fields that you have. Also I do notice that even on the same archive some posts have the document stored in the Types field and some have it stored in the Document default field, this is why some posts do not have their documents attached.
This was added in order to differentiate the different conditional statement that was being used as well as to provide a link to the post where I can view the edit screen to check the fields.
I've since removed this and the items should be displaying as intended.
