Not really, I think it just got confused, but as I said the two dns
roles need authentication. this is because the code that transfers them
is very different.

Again, I think that because you initially tried without authentication,
this did something and the later attempts didn't like it.

As I said, if everything is working correctly now and the FSMO roles
are being shown as belonging to the DCs they should be, then there
shouldn't be anything to worry about.
