For Recruitment module, I have created a job experience model for the applicant. I want the user to fill up the experiences when creating the application. When I add the form to the UI (I'm adding it to the notebook), by default, only the description shows. If I edit the form and add any field which I had created for the job experience model, the chatter disappears from the applicant.

I can still see the chatter in odoo studio, but it doesn't show up in UI anymore. I don't know what it causing this or how to solve it. If I remove the job experience UI, chatter shows again. How to approach this.

Using odoo v16.
