Lost connection to 50hz network

Had a similar issue quite a while back, but it 'healed' itself.  Unsure whether to start a new discussion or find and continue the previous one.

R7000 router with windows 11

I have two networks -2.4ghz which I'll, rather uncreatively, call Network24 and a 5.0ghz I'll call Network50.  Network24 works perfectly.

The problem is I can get NO devices to connect to Network50.  Adding a new device to Network50 finds no such network.  Using my Android phone, Network50 doesn't show in Settings on a list of Networks.    On Android Wifi Manager, I show 4 Network50 networks - all showing a a channel of '?.'  Before this recent loss of Network50, I could 'see' and connect to Network50 using channel 153, BUT, also 4 more Network50's all with a channel of '?.'

Both networks use WPA2-PSK.  Network24 uses channel 10.  Network50 uses 153.  What are the 'bonus' Network50 listings and how do I remove them?  How do I regain the ability to use Network50?

    What Firmware version is currently loaded?
    What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?

     

    Try channel 1 and 40 on 5Ghz. Or try setting manual channel 1, 6 or 11 on 2.4Ghz and 40 to 48 channel on 5Ghz.
    Any Wifi Neighbors near by? If so, how many?

     

    What security modes are you using? WPA2/AES Only is best.

     

    Try enabling Beamforming, WMM and MIMO(MIMO may or may not be needed) and WMM. Under Advanced Tab/Advanced Settings/Wireless Settings

      Set Network50 to Channel 40.
      Network24 is set to channel 10
      Neighbor wifi that show on Android setings is 4.
      Maybe I'm reading your security suggestion wrong. I don't have a choice of "WPA2/AES Only."

      Your last suggestion > "Try enabling Beamforming, WMM and MIMO(MIMO may or may not be needed) and WMM. Under Advanced Tab/Advanced Settings/Wireless Settings" I'm completely lost.
