Old SSID Name is still active when searching for wifi on smartphone

Hi, so recently a technician came and swap out our main modem due to the old one constantly cutting off internet service. We receive new a new SSID but the old SSID we had before is still visible when you search for wifi on your phone. The old standard Telus name is there as well as the 2.4g name. Currently, we have the new SSID for 2.4g and 5g but the normal new SSID is not visible for some reason. What I'm guessing is because we have two webq6000 extenders, one of them might have not been reset during the exchange of new SSID. It would be great to know how to get rid of the old SSID from showing. Also, when the technician left, the lights on the two wifi extenders for 2.4g and 5g were solid, but as 2 days have passed, the two lights have been blinking slowly off and on. Is that normal?

Thank you in advance for any advice given
