Why BSP project ignores "disable generation" ?

Hello,

I encounter this strange behaviour: I try to disable file generation of speciifc HAL driver file.

Yet, although I change it to "-" with "disable generation" and saves the settings

I verified that in xml there are addition lines:

    <IgnoredFileInfo>
 
        <componentName>altera_generic_quad_spi_controller</componentName>
 
        <fileName>altera_generic_quad_spi_controller.c</fileName>
 
    </IgnoredFileInfo>

Yet, on clicking generate bsp, it regenerate the file, and also remove the xml lines from setting, and in gui it also appears as enabled generation.

Any idea why it ignores the setting ?

I'm using quartus 15.1.

Thanks,

ran
