The last update I got from Catsone was on 18th June:
This is a known issue and we plan on fixing as soon as we are able, but I do not have a date for this.
Because of this bug, we are able to offer a free career portal branding service which uses our hosted careers page and matches the style of your WordPress site. This page will help you explain more:

What we have decided to is use the Custom Design feature within Catsone to match our branding and load the jobs board into an iframe on a specific WordPress page. We had a time limit to get this live so this was the best we could do to work with it, but it’s obviously not ideal.
