"Next Step" Button in "Create offer" Screen is Disabled

. . . but I filled in all the fields, and there’s no red/error showing. What could it be?

Details: The Bisq status bar at the bottom of the app screen looks okay; “Synced with Bitcoin Mainnet (via Tor) at block 848923 ; v1.916 ; Bitcoin network peers: 5 / Bisq network peers: 8”. Green dot and onion icon.

if it is a bitcoin offer, all you need it btc amount / fiat amount (one of the two) and premium % (and obviously a payment account must be selected from the dropdown at top), when something is missing it is usually indicated by a red background in the incomplete field
