Descriptive flexfields not visible on Request Learning-page

Content

Hello all,

we have the following problem:

We have created some flexfields for "Learning Request Additional Attributes" (Flexfield Code: WLF_LEARNING_REQUEST_DFF), but they are not visible at the "Request Learning"-page. 

We tried this before on our Test environment and they are actually dispplayed there.

We have already tried to activate them via HCM Experience Design Studio by using the same settings as on the test environment, but the flexfields are still not visible on our Production environment.

When using the Page Composer the "declarativeComponent", which is responsible for showing the flexfields on the test environment is not visible. (please see attached screenshot)
