HELP - Why does the ROI depth map on UHP camera not adjust in Mech Eye?

I would like to know why does the ROI not adjust to a new ROI after being defined in Mech Eye.

Below is the target ROI:

Below is the result of depth map still using the default ROI:

FYI this was via Mech Eye Version: 2.1.0

It is because of the Capture Mode you used.

For Mech-Eye 2.1.0, the ROI is only effective when the Camera 1 mode is selected, and is ineffective when the Merge mode is selected.

This information is also outlined in our documentation, please refer to Capture Mode.
