Job overview has no styling

Hi there,

I have recently encountered a problem with my installation. It may have come with today’s latest update, but I’m not entirely sure.
Apparently the styling of my career page is missing. (see: https://physio-kara.de/karriere/) It looks to me as if the CSS sheet is not being loaded. However, I have linked the page in the settings and also already deactivated the plugin like Autoptimize etc that have an effect on the CSS files. However, I have not found a solution.
FYI: on a single job ad page, everything works flawlessly!

Is the problem possibly on the plugin side?

Thanks in advance
Tobias
