MD3 Adjust groups

Hello

Is a first time I have this problem wich the MD3 .
When I want adjust my parameter since the MD3, is not possible.
In my programme, I Have créated the adjust groups ("Réglages")
with a PIN code

When I look the MD3, I have a green clamping for indicate to the user that there is a PIN code.

with the Up and Down button , i select my adjust group and i push on the ok button and i write my PIN code.

After, I Want select the Function parameter but it's not possible. I am blocked and I have another green clamping.

Its possible to tell me why my Fonction parameter is boqued ?

For information, I have a 4.03.27 Iqan Version

Thank you for you help.
