[Gelöst] I cannot translate the changes through to the .com domain

I run two websites: versteckter Link and versteckter Link.
The .nl version is in the lead. The .com version is the translation.
Please note, this used to be the other way around!

I am able to edit the 404 page on the .nl domain. But I cannot translate the changes through to the .com domain. Oddly enough on the translation page the .com domain is shown as the original. Not the .nl domain. Therefore I cannot edit the 404 page on the .com domain.

Please help
