Max Simultaneous Tracked Images problem

I had recently updated my Unity project from Vuforia 9.8.8 to Vuforia 10.11.3, and I needed to do some modifications in my code for it to properly works.

Almost everything is working fine, however, for some reason, the configuration of MaxSimultaneousImageTargets is not working for my app when I run it in my smartphone if I update it in real time.

In the Vuforia configuration, I set to start with the value of Max Simultaneous Tracked Images to 1. But in some scenes of my project I need to change it to another value, like 10. When I test it on Unity, it works, but when I build the project and run the app in my smartphone, my scene apparently ignores the updated value. If I start the Vuforia configuration with the value 10, I can set it to 1 in real time for the first scene while debugging in my PC, but again, when I build it to run on my android device, it ignores the updated value.

In Vuforia 9.8.8 this was working just fine for each scene: VuforiaUnity.SetHint(VuforiaHint.HINT_MAX_SIMULTANEOUS_IMAGE_TARGETS, 10)

Now with Vuforia 10.11.3, I needed to change to this line, but it is only working while I'm playing the app on Unity: VuforiaConfiguration.Instance.Vuforia.MaxSimultaneousImageTargets = 10;

I dont understand why this is happening.
