Section Heading, Icon box and Portfolio settings not loading up

Hi,

I recently changed from Visual Composer to WPBakery Page Builder and it seems that it broke some element settings on the dashboard.

Every time I try to access the settings of the Section Heading, Icon Box or Portfolio elements (by pressing the pencil icon), it opens the settings box and it seems that it’s loading but the settings are never showned. I really don’t know where to go from here because the website is not broken, everything is showing up as it did before I made the switch to WPBakery so I’m not sure what’s wrong. Any clues?

Thanks in advance!
