BUG: Switch is not able to show data from collection!

Hi.
On page (static) there is a Switch which is bound to boolean data field in collection.
When site is running it is never able to show actual data from collection!
Here is a picture:


Why is that? What is wrong? How to make Switch to show actual boolean value from specified field in collection?

is your dataset set to read only or read / write or write only?

Dataset is confiigured with default settings - Read-only mode.
