CPT Links not translated

Hi!

I am a paid customer, also already filed a ticket, but no response yet. So, I hope maybe someone else can help me (too).

I am experiencing issues with the links. I am using Bricks Builder and Meta Box. I have created a couple of custom post types with Meta Box. For some reason, the base slugs are not translated. I checked the database ánd the strings settings and both show the right translations. For some reason, the cpt base slugs are not working properly, while everything seems to be set properly. So, an example is that my slug in dutch is ‘/over-kade/’, in Dutch /nl/over-kade/. The link should contain ‘/en/about-kade/’ instead, but it shows /en/over-kade/. In the database ánd in the strings, it is both set to /about-kade/.

After searching for hours to figure this problem out, I am clueless at to what to do next. I prefer not to switch, since everything works fine except for this issue.
