32h8 feature code issue

We have a customer trying to upgrade the feature codes on a 32h8. This is what he says:

I am having trouble updating the feature passcodes. When I go to configuration access level in iTools and write the Feature Passcode, it immediately changes to value 151 as soon as I press enter. Moreover, Feature Passcode 2 is read only, but has changed itself to 2247.
