Ampersand characters at Tag Panel options

With v3.05 on Win 10, the options Tag Panel pane as some extra "&" characters, E.g. "Tit&le", "Art&ist", etc. I'm new to Mp3tag, are those supposed to be there? Attached is a screen-capture of what I'm referring to:

Yes - they designate the Alt-Key combination to jump to that field directly. No bug.

Oh, I see. After pressing Alt (the first time), the tag panel also underlines the relevant shortcut key for each field, that's pretty handy!
