Problem I am having. – Jetpack Joyride Review

I really enjoy the game. Stupidly I once bought just the dolaran and then now just bought the back to the future whole pack..but whatever..they are fun. But I am having an issue. Everytime I go to play the game the B2TF Guitar doesn't stay loaded. I have to go to restore purchases and then I can select it, but then when I go to play it switches to the machine gun jetpack..I can pick it..I can see it as my jetpack when I look at my profile but it wont let me use it. Similar for the hoverboard. For it to show up I have to restore my purchase everytime I open it..I didnt know where else to write this so I put it here..can anyone help with the issue?
