How to edit my first name in Callsign Update and make it work in Logbook?

I edited my First Name + Initial in Callsign Update and saved. But when I added or edited Logbook QSO (logbook.qrz.com), I find my name in Sender Info > Operator hasn't been edited and I can't edit it. I want to know how to change my first name in Logbook? Thanks.

 

Have you tried logging out and logging back in to see if it changes?

 

The name shown in BG4LZY - Callsign Lookup by QRZ Ham Radio changed correctly. But in logbook.qrz.com, the OP name doesn't change.
You can see the yellow circle below.

 

Go to https://logbook.qrz.com/logbook, click on "Settings" (Blue Circle) then "Logbook Properties" (Red Circle). Scroll down and change the "Operator Name"

 

Thanks! Problem solved.
