ASM on Mode Transparent (Learning) doesnt learn some parameters

I don't understand what you mean by "the alerts are very dynamic depending on where you click on the menu".

Have you set 'Unknown parameter' to be Learn and Alarm? I suspect that you are getting confused between different violations. To build a policy automatically, you need to send lots of valid data through the policy. Otherwise, you can manually create the policy using Learning Suggestions. These work with the blocking mask and the entities to create the ASM policy.
