The short answer: German is not English.

The German language allows for both male and female forms of most job descriptions(like with actor and actress). It doesn't help that we have a male, female and neutral form of "the" which are seemingly randomly used for certain words, and often also differently when used in a plural form.

This mixed with gender debates has lead to a lot of controversy and many more or less wild suggestions for "fixing" the language.

The explicit mention of male/female has been mandatory for quite a while, and now that "diverse" was added as a third officially recognised gender this is now required as well. The whole reasoning behind this is that hiring decisions must not be based on gender, so companies also have to clearly indicate that - whether that actually reflects reality is another can of worms.
