intrasite rep with mor than 1 store is not working

I tried to use the Script for an Intrasite replication. However, it is not working and will cancel with the following Output:
`Get-PvsStore : Cannot bind parameter 'StoreId'. Cannot convert value "System.Object[]" to type "System.Guid". Error: "Guid should contain 32 digits with 4 dashes `

In my case, this line returns more than one store back and this is not supported
`$IS_storeID = (Get-PvsServerStore -ServerName $IS_srcServer.Split('.')[0]).StoreID[0].ToString()`

Start by running the Get-PvsServerStore command from the reported $IS_storeID assignment against a server with multiple stores and trace the value passed to Get-PvsStore. Review the surrounding replication script to establish which store should be selected or handled, then verify the script completes without passing an array where a single StoreId is required.
