Matlab AUTOSAR receiver dataelements initialization

Deart Support!

I have some question regarding the AUTOSAR dataelement initialization.

Why matlab cannot generate init value for AUTOSAR receiver dataelement when the datatype of the element is ENUM or BUS structure?

Why matlab cannot generate code and arxml if error status is created for port and init value is higher than 255 and port datatype is uint8 base type?

Why matlab is reinitializing (back to 0) all of the initial values for dataelements after code generation and diagram update?

Thanks.
