Code autocomplete feature and defines not recognizeable with STM32F429DISCOVERY

Hello,

I created a new project based on the STM32F429DISCOVERY Board with CubeMX (newest Version) for True Studio (newest version). sadly when i add some defines in main.h under the user code section, the defines are not recognized after safe and rebuild in main.c or any other .c file including main.h. As if I didn't have changed anything. This behaviour is only for the mentioned Board under CubeMX Code generation. I used short directory names and project names.

Anyone knows of this and how to solv this?

best regards

Benjamin
