Unable to resolve identifier

Hello,
 
I have generated a code with MCC where I' like tot toggel RC9. The board is a Curiosity Board with PIC32MM0064GPL036 - RC9 connected to LED.
When I build I get the following error when I use ...
IO_RC9_SetHigh();
Does anybody have an idea, why the complice complain? I use MPLAB v5.40 and XC32v2.41

This is coming from the pre-parser connected to MPLAB X IDE. 
The pre-parser doesn't have the knowledge of the symbol / isn't able to resolve the symbol. 
However, the code should build fine and compiler will complain if there's anything wrong with the code. 
 
To fix the IDE's pre-parser you must submit your code via a support ticket.
