After a LastPass import many passwords (not really passwords but were Secure Documents) were left in a state where I could not access them in the mobile app. When I tried to select the password entry with a blank password I got the error message: Passord cannot be empty (in red) and I was not able to view the data in the Description field (which is all that is in this “password” entry). So I pulled up the record and edited it in the browser and set a random password. After that I was able to view the data in the description field in the mobile app.
I suggest in your conversion program from LastPass to leave the recrods in a state that can be accessed from the mobile app, like maybe put in a random password or something so the mobile app can pull up the information associated with the “password” entry.
It would be better to actually add secure notes to the CE version.
