Preferences - Tablet - Size sensitivity : Set to 0 but still get size change?

[Susan]

Hi all, just getting into working with a new tablet ( Wacom Intous Pro, windows 10, Z4R7)
I wanted to try the tablet with just Z intensity increase as preassure is applied and no brush size change, so I set Size Sensitivity to zero under Preferences - Tablet, but I still get a size change when I apply preassure. How do I turn off the preassure sensitivity for size? Settting the Z Sensitivity slider seems to work to turn off when I set its slider to zero, so wondering why this is not working for the size slider?

Thank you for your replies

Sorry posted to soon perhaps, just found that;
I need to turn on Use Global Settings in brush pallet - tablet .
That seem to fix it.
