In Masternode list: "I see the list of Masternode e there is my Masternode Ip but i see only one, indeed I see others Masternode Ip duplicate that make me think they are more than a masternode"
It would take a command to see my Masternode attvi.
I think you can use the following command tp get a full list of all masternodes
masternodelist full
or the following to get the status from your masternode
masternode debug
I've tested it out and when it says masternode started remotely means your masternode is already running so you should be good.
Not sure what's up with the masternode list but I noticed entering my public IP into the conf file didn't work which would make sense offcourse. Running the masternode in the wallet you'd use for public IP the localhost (127.0.0.1) that worked for me and been getting rewards for the past 2 days.
