There are less extreme ways than “delete all your decks” to force the Default deck to appear. So if you don’t want to try that – this should work:
- Manage Note Types > choose “Basic” > Cards > top “Options” drop-down > Deck Override
- Start typing the name of a deck and a list of existing decks will appear.
- If the theory holds, that list doesn’t include a deck called
Default
, but it does include a deck calledDigital Logic
– select that deck. - Add a note of type “Basic” – that card should be created in the “Digital Logic” deck.
- Rename that deck to
Default
, which should free up the deck name you want – rename “Digital, Logic” toDigital Logic
- Clean-up – turn Deck Override off for the “Basic” note type – delete the note you created (and the Default deck should disappear).
[If that doesn’t work, I have another idea …]
