Vuforia simultaneous tracked objects

A few months ago, I started developing an app with vuforia in unity. The purpose was just to show a 3D model when a user holds their mobile over a marker. It worked fully without any issues.

All of a sudden, the objects on the markers no longer move independently from one another. By this, I mean, originally, I could have say two markers being tracked at once, showing both models, and the user would be able to rotate one of the markers and just the object on that marker would be affected.

Now, when the markers are detected, it places the objects in the relative world space to the first marker. This means, if in the editor the markers are two units away, no matter how the markers are orientated in real life, the application just shows the objects always two units away from each other as if they are both children of the same marker (the are not, I have checked this)

Please comment or ask for further details if needed

Thanks in advance for your help, David Phoenix
