It is a question about apostille.
Suppose you have an HD account signed by Alice and Bob. (2 - of - 2)
Here, Alice will do a notarized update or message transmission.
In this case, NanoWallet can choose either Normal or Multisig.
If you choose Multisig, it will behave as expected, but selecting Normal creates an HD account under the HD account. regardless of Bob
Normal is a bit confusing behavior, but is this expected usage expected?
If it is not assumed, I think that it is easy to use if you can not select Normal.
