EXCLUSIVE Choice Groups not responding to setselectedindex or flags

I am currently working on a small application for the Motorola A925, where I have an options form.

This forms contains some EXCLUSIVE and MULTIPLE lists. If I accept the changes than they are saved and stored. However if I cancel, than I am hoping for the app to set the lists back to how they were before entering the form, but using setselectedindex or setselectedflags. I have tried both methods and they both work on the wireless toolkit emulator. However on the A925 emulator and phone, it does not work properly.

The multiple lists are set back to how I wanted them, but the current selection is accepted in the EXCLUSIVE lists. Basically, if I enter and a selection is YES, but I change it to NO, and cancel than when I go back in, it should be YES. However it is still NO, despite using the setselected.. methods to change it.

Is this a problem with the Motorola handset, or is there a way to do this, as it is working on the SUN toolkit.
