Hi Paul,
Glad you like WIT.
It's most likely an issue related to Jobify theme. I have already tested WP-Job Manager, and all is good.
Unfortunately, I cannot test Jobify theme because I do not have it.
I suggest you ask Jobify developer for support on this one. I will gladly fix any issues they find in WIT.
If that does not work out, we can work on this together, but that would take more time.
Best regards.
