MSP430FR6877: Setting GPIO pin to high is not effective

Part Number: MSP430FR6877

I am configuring GPIO 9.6 as output:

GPIO_setAsOutputPin(GPIO_PORT_P9, GPIO_PIN5 | GPIO_PIN6 | GPIO_PIN7);

GPIO_setOutputLowOnPin(GPIO_PORT_P9, GPIO_PIN5 | GPIO_PIN6 );

Then I am trying to set it to high:

GPIO_setOutputHighOnPin(GPIO_PORT_P9, GPIO_PIN6);

But when I check P9OUT6 just after stepping over the set to high function, I find it 0.

So is there anything with the software/hardware that can cause that?
