Blueprints might get into a corrupted state when they are inherited for a big number of times. Starting from a C++ class, if you then create a BlueprintClass from the C++ class, and keep creating new child classes from the created onces, the Blueprint might get corrupted. This corruption state makes some components details pannel not appear. Also, in this corruption state, changes on Parent Blueprint Properties do not reflect in child Blueprints. The user attached a repro project where the issue can be seen easily.
*Repro project already attached to the case, where the issue is already present*
1- Create a C++ class, inheriting from ACharacter for example.
2- Create a Blueprint from the created C++
3- Keep creating Blueprint classes that inherits from the previous Blueprint class.
4- Review the CharacterMovementComponent, and see if the details pannel appears correctly. If it does, keep repeating step 3 until you don't see displayed the details pannel.
