Describe the bug
A clear and concise description of what the bug is.

To Reproduce
When recognizing images, the update information is wrong. After I recognize a picture, I hold the picture so that it does not appear in the camera, but the picture is still returned in the update.

Expected behavior
Uptate will return information that is consistent with the actual situation, or is there any way to clear the currently recognized pictures, because I found that the information returned in add is always correct.

Actual behavior
`ARTrackedImageManager m_TrackedImageManager;

void OnEnable() => m_TrackedImageManager.trackedImagesChanged += OnChanged;

void OnDisable() => m_TrackedImageManager.trackedImagesChanged -= OnChanged;

void OnChanged(ARTrackedImagesChangedEventArgs eventArgs)
{
foreach (var newImage in eventArgs.added)
{
// Handle added event
}

foreach (var updatedImage in eventArgs.updated)
{
 // Handle updated event
}
foreach (var removedImage in eventArgs.removed)
{
 // Handle removed event
}

}`
I just follow the official example for image recognition. I get the currently captured object in add and update.
