Note not showing in uke tab

UPDATE: fixed, but I’ll leave it here in the hopes that it benefits someone else.

Surely I’m missing something here. I’m afraid I’m showing my ignorance of ukulele and tablature, but I can’t figure it out.

In this example, the baritone uke is tuned to EBGD. Shouldn’t the selected note display a 4 on the bottom string?


UPDATE: I found the problem. The bottom string was tuned to D4, not D3!


That kind of flummoxed me when I first tuned a ukulele. I had been unfamiliar with how ukulele were tuned and had expected each string to be lower than the one before it…
