Page Turn Effect Bug

I get an error message when I try to turn off the page turn effect in the global Navigation Menu.  I do not want to have the default page turn arrows in all four corners as usability experts have determined that kids hold the ipad from the bottom left and right corners of the ipad.  Therefore I want to disable this feature and just use my own buttons on the top left and right of each page. I assume turning off Page Turn Effects is the way to do this?  If not, please advise.  But do note the bug below.

To reproduce, select Page Turn Effects > None 

InteractBuilder Version: 3.2 Build 311

Device: MacBook Pro

Processor: Intel Core i7

Memory: 4 GB
