Page builder not working

Hi,

We are using wordpress for our website. Last week I did the update for wordpress and all the plugin’s. I’m using also page builder by siteorigin. We have a few websites for other languages.
When I want to work at our website www.greenenergyholding.net the tab “page builder” doesn’t appear on the screen “pages” while it’s downloaded and active.
but when I work on the same site but different language www.greenenergyholding.net/FR everything is how it should be.
Can you help me with this plugin on the first website? I’ve been searching the web on possibile solutions but I don’t find anything.

Hoping you can help me.

Thank you
