F5 ASM File Type Learn Explicit Entities in Rapid Deployment

and to add a final piece i believe the extra file types won't be added automatically to the file types list you will have to do this via the manual traffic learning section.

see also this from the help: "•When the Automated Policy Builder is not running, the system suggests that you add explicit entities that match the wildcard entity."

if all this doesn't help you you might want to explain a bit better and provide some more configuration screenshots to show how the system is setup.
