I checked this already and it really affects most of the functions.
My findings so far: I got rid of message for the first classes in the unit by moving up the implementation to the beginning of the implementation.
So I assume there is something in the implementation section which stops the compiler recognizing the methods.
I already checks for global functions or variables or other types - but didn’t find any suspicious.
There is no “end.” since it actually can check the implemented functions and some of them are ok, others have still problems.
