Changing instruments

Hi brains trust
I have been on a long journey attempting to arrange a string quartet accompaniment for Vedi se t'amo, the soprano aria by Haydn from "Armida". First I tried to import the piano and voice score and extract from that, but that was failing so I did as someone suggested in that process and inserted staves in between the piano right and left hand. That was problematic. I pretty much arranged from scratch. However, now I am attempting to extract parts from the score and its not happy, I fear because all the voices are misnamed. I attach some screen shots, Can anyone help.
