Student admission troubles

I have details with student applicant in an education domain.

I create a student applicant, then in another browser i create an student account in the registration page, i receive the mail, create a password, and when i try to apply to the student applicant published in the frontend, i only see a message that says “nothing to show”.

i’ve enabled in the role management permissions for student applicant and web forms in the student profile but i can’t make it work it.

What is wrong?

In version 11 i could do it without problem, in fact, i tried to install V11 and now neither works the student applicant, i get this message when i try to see in the website the student applicant created “{{ title or (("{0} List").format((doctype))) }}”, i see that even in the virtual machine image that is in the download page, what happened?

Thanks in advance.
