Error while changing configuration “Are you sure you want to do this?”

Hello All

I am trying to do the following changes to the setting of Job Manager –
1. Delete the listed job by selecting the job and opting “Delete” from bulk action drop-down.
2. Changing the information fields required to post a new job

However, I am getting “Are you sure you want to do this?” page without any Yes/No option when I apply these changes.

My objective is as follows –
1. Be able to define what information would get captured, and displayed, in my job listing
2. Be able to display a list of all jobs on the Listing page
3. Applicant be able to select one, or more, jobs to apply.

Any help will be greatly appreciated.

Thank you.
