Pairing second Lutron system with Alexa

I own 2 homes. In the first home I have a Caseta system that paired easily with Alexa. I have now installed a second Caseta system in my second home and had to establish a second Lutron account in order to pair the second system with my WiFi in house number 2. The system works flawlessly but I am not able to pair my Alexa app with this second system. Using my App or using Alexa she is not able to discover the casita wireless switch. I suspect this is because of the second Lutron account I had to open, but I am not sure. I am not given the option to download a second LUTRON app on Alexa. I called tech support and was told that I should try the system support for Lutron. I am hoping this is the correct lace to ask my question. Thank you. MarkD
