Missing include file path after add it

[SteMMo33]

Arm cross compiler project with GCC compiler.
Generated a Arm Cross Project.
Inserted a new include path on 'GNUArm Cross C Compiler' - 'Include paths'
If I check the 'All options' content on the parent window I see the selected path in the generated commnd line:
-I"C:\Progetti\dbTechnologies\testSTM32\testSTM32_CMSIS_RTOS_FreeRTOS\src\CMSIS-FreeRTOS\Source\include" -std=gnu11

Right click on project + 'Build Project'
The used command line does not contain the selected include path, but a previous not-valid path:

Building file: ../src/CMSIS-FreeRTOS/Source/portable/Gcc/ARM_CA7/port.c
Invoking: GNU Arm Cross C Compiler
arm-none-eabi-gcc -mcpu=cortex-a7 -mthumb -O2 -g **-I"C:\Progetti\dbTechnologies\testSTM32\testSTM32_CMSIS_RTOS2\Drivers\CMSIS\RTOS2\Include"** -std=gnu11 -MMD -MP -MF"src/CMSIS-FreeRTOS/Source/portable/Gcc/ARM_CA7/port.d" -MT"src/CMSIS-FreeRTOS/Source/portable/Gcc/ARM_CA7/port.o" -c -o "src/CMSIS-FreeRTOS/Source/portable/Gcc/ARM_CA7/port.o" "../src/CMSIS-FreeRTOS/Source/portable/Gcc/ARM_CA7/port.c"
../src/CMSIS-FreeRTOS/Source/portable/Gcc/ARM_CA7/port.c:34:10: fatal error: FreeRTOS.h: No such file or directory

If i go back to the settings window I see the wanted correct path!
How it is possible?
Any idea?

After 'Clear project' command nothing change.

-- EDIT

If I add the path as Include System Path (adding to the same path in the Include Paths -I), I see the new path under -isystem PLUS the uncorrent path with -I option:

Building file: ../src/CMSIS-FreeRTOS/Source/portable/Gcc/ARM_CA7/port.c
Invoking: GNU Arm Cross C Compiler
arm-none-eabi-gcc -mcpu=cortex-a7 -mthumb -O2 -g -I"C:\Progetti\dbTechnologies\testSTM32\testSTM32_CMSIS_RTOS2\Drivers\CMSIS\RTOS2\Include" -isystem"C:\Progetti\dbTechnologies\testSTM32\testSTM32_CMSIS_RTOS_FreeRTOS\src\CMSIS-FreeRTOS\Source\include" -std=gnu11 -MMD -MP -MF"src/CMSIS-FreeRTOS/Source/portable/Gcc/ARM_CA7/port.d" -MT"src/CMSIS-FreeRTOS/Source/portable/Gcc/ARM_CA7/port.o" -c -o "src/CMSIS-FreeRTOS/Source/portable/Gcc/ARM_CA7/port.o" "../src/CMSIS-FreeRTOS/Source/portable/Gcc/ARM_CA7/port.c"
