Accordion and dropdown toggles are autoclosing

Throughout the site I have several accordions that are great for displaying my data, however, with the recent updates, they stopped working.

I’ve looked through the forums, and so far I found only old threads and decided to open a new one.

The problem scenario is like this: You click on an accordion, it opens, but right after reaching the end of animation, it closes back down.

So far I’ve tried:

• Using different plugin (elements kit and royal addons)
• Recreating it from scratch
• Deep-dive in the settings and not finding anything.
• Updating everything.

Please help and many thanks in advance!
