Gb Minor-Major 7, written Gbm(maj7), is built from Gb, Bbb, Db and F: the root, minor 3rd, 5th and major 7th.
Its 3rd and 7th, Bbb and F, are its guide tones: they say what kind of chord it is, so voicings are built around them and the root is often left to the bass.
In the progressions here, Gbm(maj7) is the imaj7 of the Minor Line Cliché in Gb.
