EZMotion 3 in 1 cannot be added to VerLite


I’m trying to add my EZMotion 3 in 1 sensor to my VeraLite controller. But the last of the four sensors I have purchased can not be added. To add the sensor I place the controller in Exclusion mode and push the button on the motion sensor. The Status bar in the controller interface states that the device is detected but doesn’t proceed with the remove procedure.

VeraLite firmware version: 1.7.439

I hope you can help me with this issue.
