This bug was reintroduced
Events TB Archive Page
This archive page was created with the Divi theme builder and currently has a bug.
The background images load in the wrong order. When using pagination, the background images from the first page remain unchanged when clicking "next" to view the following pages.
Events as Normal Page
This is a workaround to use a normal page instead of creating an archive page with the Divi Theme Builder, which currently has the mentioned bug.
Using a normal page with the exact same layout as the TB Archive Page example works perfectly. The bug only occurs when using the Divi Theme Builder for an archive.
