WP Job Manager and qTranslate X: no translation of some fields

WP Job Manager is a plugin to manage job offers. It has a shortcode which outputs a list of the jobs. using qTranslate X almost every string is translated except for the job titles.
I know wp job manager works with WPML, but I would love to get it to work with qTranslateX as well. This is what happens:
In default laguage (Dutch) the job titles and all other strings in the list are in the correct language.
When I switch to English, everything lists in English well, BUT the individual job titles are still in Dutch. Plus, the titles link to a wrong permalink (it puts ‘en/job/’ in front of title instead of ‘en/vacature/’ <- ‘vacature’ is dutch for job )

What is most important for now is the jobs being shown in the correct language.
Maybe language codes are stripped from the job titles on output of the [jobs] shortcode?

From WP Job Manager support i got this reply on the question: ‘

Hi
This may be related to the ajax request – it may not know the language the request should be made in,

For WPML we added this:
https://github.com/mikejolley/WP-Job-Manager/blob/master/wp-job-manager.php#L114

QTranslate may need something similar, but I’m not familiar with the plugin so I cannot say if they have their own version of this.

So far I had no luck while trying to solve the problem.
Has anyone had this problem with WP Job Manager or a similar problem with another plugin? And most importantly, does anyone know what might be causing this problem (and/or how to solve it)?

Thanks in advance. Any help would be welcome!
