The third voice from the top lowered an octave. The dropped voice becomes the bass, which is why a string is skipped.
BmMaj11 is B, D, F#, A#, C# and E — BmMaj9 with the eleventh added on top.
It sounds dense and unresolved. Something is always omitted; the ♭3 and the natural 7 are what must not be.

Minor tonic — the melodic minor as far up as a guitar carries it.
Also written BmM11 or Bm(maj11). The same chord either way; which spelling you meet depends on who wrote the chart.
The same operation one voice further down: the third voice from the top falls an octave and becomes the bass.
That leaves a bigger hole under the top three notes, so a string gets skipped: the muted string in the middle is the shape, not a mistake.
BmMaj11 has 10 of them, on strings 5-3-2-1 and strings 6-4-3-2, from the 2nd fret up to the 12th — every inversion the chord has: B in the bass, D in the bass, A# in the bass and E in the bass. The one to learn first is the B shape at the 2nd fret.
5 of them sit on strings 5-3-2-1, so you can run the inversions up one set without changing strings — which is the whole reason to learn them as a family rather than as separate grips.
Start with x20320 — no barre and 2 open strings. 1 of the 8 shapes here sits in open position. 5 of the 8 need a barre. Together they cover the neck from the 2nd fret to the 15th.

The same notes rebuilt from scratch give 7 shell, 15 drop 2, 24 rootless and 6 open string voicings, each on its own page.
Tensions. A shell of BmMaj11, root, third and seventh, leaves a string free, and the tones that belong over it are the 13 (G#).
How you get to it. The turn that lands on BmMaj11 is C#m7♭5 to F#7♭9: the ii and the V of B minor, which is where a minor tonic is usually arrived at rather than simply begun on.
Every note of BmMaj11 is in B harmonic minor and B melodic minor.
Change one note of BmMaj11 and you have Bmaj11 (the minor third becomes a major third), Bm11 (the major seventh becomes a flat seventh) or BmMaj9 (drop the fourth).
BmMaj11 is a minor chord — root, minor third, fifth. Minor chords on every root.
