That seems odd. In my experience GnuCash won't allow two accounts in the
immediate context with the same name (despite the fact that internally GnuCash
doesn't use the human readable account name at all). I'm not sure how you
succeeded in that, but your remedy should be fine.

In looking at my account tree, I see two accounts with the same name with
the same parent. That seems wrong. In looking at them, one is a
placeholder, the other is a normal account.
Now that I see that issue, I have moved the normal account to be a child of
the placeholder and renamed it.
