i have a problem 360 image inside sphere in vuforia making AR experience

Hi i have created AR experience 360 image( indoor living room) inside a sphere with position zeros, and the AR camera in the zeros position , but when i run the application and aim to the image target, it will work, but the 360 image ( living room ) will appear very clear, but it is spherical, also i have another problem which is; i will stay in the centre of the room not moving , whereas when i did this experience using AR foundation it works perfectly, the room was a room and I can move inside it as I’m really walking inside a room with my mobile. Can you help me please? Thank you
