TV Shield – kodi running in background

Hello

i got the following problem – if you hit the menu button twice on the Nvidia Shield your app should run in the background and you can switch between the apps
but when i go back to kodi – it will not run from where i left it – but will just start from the begin again – starting with the kodi logo – anybody know if there is a way to fix this – so that i can come back just where i left it ?
