Howdy guys,
Sorry for being late jumping in here - I've been down south helping my parents celebrate their 50th wedding anniversary
Marcello, the additional "i" in the chord name is an unfortunate bug that shows up sometimes for some chord types. For now the workaround is to simply double-click the chord name and manually delete that "i".
Sorry for the bother, but it is getting fixed for the next release
ttfn,
Sherry
