Issues with the binding relationship between devices, applications, and instances

### Current Behavior

When I create a device, the device is bound to the application, but the actual snapshot needs to be sent to the device through the instance. At this time, we can only manually switch from the application to the device. I found that the device table has the application ID by checking the database. I modified the database and saw the effect as shown in the figure.

Is there any other reason

thanks
