Hello elle,
I am going to take a crack at this, I could be wrong but something to look at.
I suspect the "copies" you see are networks that were previous connections having the same name but some other criteria such as a different IP address, maybe a different router you have installed ect. Please look in the following area in the GUI - setup>advanced setup>Network protection>Known networks>edit after hitting edit see if you see the same Home and then Home 2,3,4 in that list.
You only need the one you are using, you can delete any unused networks here, I am guessing
