Divi Blog Grid Linking to Wrong Posts

After the update to WP 5.5 and Divi 4.5.7, I added a new custom post type. A previous custom post type I added prior to these updates works fine, but there’s something wrong with the new on I added following the updates. Using the exact same page template and the same Divi module (blog module using grid display) as the one that works properly, the links that populate in the blog grid whan calling to the new content type are opening up posts with the wrong content. For example, in the blog grid, there are 3 stories displayed, all show the right headlines and excerpts in the grid, and when I check the links to the posts, they show they are linking to the correct post IDs, but when the posts open, they are displaying the content from a different post ID.

Any ideas why this might be?
