Alexa not recognizing all receptacles on Smart Life Wall Outket

I have a Smart WiFi Wall Outlet Plug:

successfully installed in the Android Smart Life app, and I can individually control both 120V receptacles and the USB port via the app.

However, in Alexa, the device is recognized as a single receptacle outlet.

Alexa commands control only one of the receptacles, and the second receptacle and the USB port are not visible as separate devices.

This is different from other multiple receptacle Smart life devices (such as power strips) I have installed, where each separately controllable receptacle visible in the Smart Life app is displayed as a separate device in Alexa.

Both Alexa and Smart Life are upgraded to the current versions.
