UI checkbox interaction in the VI settings window

[fominykh]

Currently, I can reproduce the bug:

1. Add the VR augmentation to an activity.
2. Find the setting "Model", which is a language model.
3. Observe that there is some model is selected by default.
4. Airtap on the Model.
5. This opens a secondary window with a list of language models.
6. Bug 1. Observe that one of the models is selected - visually it looks like a check mark. The model in the list that shows the check mark is different from the model that was selected on the main VI settings window (see step 3).
7. Bug 2. Airtap on the model that currently has the check mark. the check mark disappears, but the model on which you tapped is selected.
