If you go to Toolset > Relationships you have created a relationship between two post types, yes?
And if you edit a post of one side of the relationship, you expect to be able to connect to existing or add new connected posts of the other side of the relationship, right?
From your description it sounds like maybe you cannot do this last part.
Is that right? Perhaps you could include a screenshot of the post edit screen where the UI for post relationships should appear.
You should also try disabling all plugins except Types and Views to confirm whether you still see the problem; whatever the issue is, it could be caused by a conflict with another of your plugins.
I logged in to your site, and went to Toolset > Relationships where I saw you had several relationships created.
I see that you have a one-to-many relationship between Jadwal and Jurnal post types for example.
If I edit a Jadwal post I can see (at the bottom) the section to relate Jurnal posts, and if I edit a Jurnal post I can see the section to relate Jadwal posts. (See screenshot.)
Everything appears to be working normally.
If there is an issue can you please give exact details?
