Hi @as-op

I did not have a look at the code as that is not my field of expertise but just tested it. I noticed two things:

• All custom fields are shown with their ID instead of their name. (see green marks in the picture)
• For Custom Fields of type "long text", the value is shown as raw text in the table, and then again compiled below the table. Is that intended? (see blue marks in the picture)

Thanks a lot, @HDinger ! Both issues are not intended and are indeed bugs. I'll fix those.
