WP Job Manager By Automattic

Hi all Ive been using this plugin for a number of years and over the last few months I dont seem to be able to change the expiry date and re entre the job onto the page, I simple want to kep the jobs available for another year and it doesnt work and slowly when jobs hit the expiry date they disappear, I had one solution 4 months ago and just copied the old info and created a new job but that doesnt seem to work, any suggestions Im stuck and Im not really good at wordpress tech.
