@W2DIY Hey Daniel,
That is because FT4 is a sub mode of MFSK. It’s set that way currently because we have had issues with people getting errors or not getting confirmations from QRZ in the past. We’ve had several people mention this and are going to be making a change that will show it as FT4 but when you export your log it will show MFSK so there is no issues with uploading to QRZ. Its on the list but i dont have a timeline of when this will be completed.
Thanks & 73
