Problems with bootstrap collapse when applied with Drupal

In a section of the page that works with drupal I am implementing four images with horizontal arrangement. Each of these images opens a collapsible panel right in the next division. The problem is that when I click on one of the images to open the panel, the same drupal (I think) hides it shortly after opening. You click it again and the panel reappears but it immediately has the effect of closing like an accordion. I leave the code.

<section id="section-categorias" class="bloquehome" data-stellar-background-ratio="0.5">
