Category filtering does not work correctly

Hi,

I am using categories to filter the imported jobs via cronjobs into fitting categories. All categories work good, only 1 looks like it does not work.

I am importing German jobs, so maybe its a language issue. I want to put Jobs with “Wissenschaftliche/r Mitarbeiter” into the “Student” category. “Wissenschaftlicher Mitarbeiter” is something like a scientific assistant.

So I created the category Student and set “wissenschaftlich” (without quotes) as a tag, but the plugin always puts the jobs containing the word “wissenschaftlich” into the general category. All other created categorys work just fine, only this one does not work.

Thanks for your help.
Udo
