When I rotate, the number of option menu items increases



I have problems with the option menu items. Everytime I rotate the device, a new set of menu items gets created and added to the existing list of menu items. This means, at the end of the chapter I start with 2 items (add crime and show subtitle), when I rotate my phone I have 4 items, when I rotate back there are 6 items and so on.

Some Google research recommended to set setRetainInstance(true) during the onCreate(), but this didn’t change anything.

Thanks for your help!
