I am trying to export my vault and I noticed that many of my username/passwords did not export. I looked at the entries and noticed some have two username/login fields and that the one I populated did not export.
Here's a picture of two accounts, one with and one without the extra login fields: https://i.imgur.com/jb5RXyh.jpg
