Unable To Select Multiple Job Types while creating/editing job listing

Previously, I was able to choose multiple Job types while creating new job or editing existing job listing on my site. I even created additional job types in addition to the defaults, which I could as well multiple-select while creating new jobs. But after the last update, I could only select one job type while creating a new job post. I also found out my primary all jobs listing page https://goo.gl/FRwp1K no longer lists the jobs. I don’t know if the issues are related.
Kindly, investigate and let me know if I am doing anything wrong. Thanks
