Submit Job only works for one user

Hello all,
I have set-up WP Job Manager on a job page.
The idea is to create users (the employees of the company) who can submit jobs to the job board.
Thus to submit a Job you need to be logged in.

The job submission works fine if I am submitting (page admin and creator of the webpage).
But once I try with another user, I press the submit (or review) button and nothing happens. I have even switched the test user to administrator rights and it still does not work.

Did anyone experience this and would be able to help?
best
Renaud
