Hi. In general, it is better to do through standard Joomla article pages, but not through Page Bulder pages. In the left position, place the module with your event buttons.
With SP PB pages you need a lot of handmade. All related pages should be exactly the same Layout 3 + 9. Convert your event buttons to the module and publish it in some position. Let's call it "Test position." In the COL-3 on the associated pages, place the Joomla addon module whith position mode and select there "Test Position".
