Page Builder by SiteOrigin causes 404 pages on secondary wpml language pages

I’ve bought the WP theme “Off the Shelf” by ShapingRain.com. This theme uses “Page Builder by SiteOrigin”.

I have a site with two domains: gdpr-logger.com and gdpr-logger.dk. The problem is that “Page Builder by SiteOrigin” is giving me 404 ERROR pages for either 2nd level or 3 level urls:

In the native site language (english), the follwoing urls work fine:

https://gdpr-logger.com/products/
https://gdpr-logger.com/products/gdpr-logger-for-ibm-notes/

In dansh:

https://gdpr-logger.dk/produkter/
https://gdpr-logger.dk/produkter/gdpr-logger-for-ibm-notes-dk/

My problem is that in danish i get a 404 on either one of the pages:

If the permalinks are set up as https://gdpr-logger.com/%postname%/ only this page works: https://gdpr-logger.dk/produkter/ but not https://gdpr-logger.dk/produkter/gdpr-logger-for-ibm-notes-dk/

If the permalinks are set up as https://gdpr-logger.com/%category%/%postname%/only this page works: https://gdpr-logger.dk/produkter/gdpr-logger-for-ibm-notes-dk/ but not https://gdpr-logger.dk/produkter/

I need to be able to make 2nd, 3rd and 4th level links in both languages.

It seems like it is the “Page Builder by SiteOrigin” plug-in messing up my site.
My problem is that this plug-in is required by the theme.

I’ve read that there has been some problems between wpml and “Page Builder by SiteOrigin” before: https://wpml.org/forums/topic/wpml-doesnt-work-with-page-builder-by-siteorigin/

Do You know if there is any fix?
