The main iVana screen provides a choice between replacing or appending existing content (see screenshot box highlight below). The default is "Append".
This is especially critical during the exterior spin when you have multiple spins, such as when the doors are closed and then open or you take spins from regular and then elevated cameras.
Make sure the content setting is on "Append". If it's set to "Replace", the first spin will be removed and replaced by the second spin.
