Properties in flowable UI

Hi there.

For my curiosity I have deployed an open source Flowable on some test server.

It looks like I don`t have all the rights in flowable, since I cant fill all field properties for most of the task/activities/etc. in in Flowable Modeler through UI. Example on picture.

I am using default admin user.

Does someone knows what I need to change in order to be able to use all the properties through the UI?

Kind regards,
