Hello - I saw this a while ago and was waiting to see if there were any replies. I can’t claim to have a full answer but I will offer something. Scaler appears to have certain chord labeling conventions and some of them don’t match up exactly with what you have above. My guess is that they are all actually there (the chords) but not necessarily easy to correlate. For example, while I was looking for an F6 yesterday I remembered that it only seems to appear as F maj add 13, which seems a bit complicated but is nevertheless accurate.
We are changing our chord nomenclature to be more standard which makes sense. We actually had that pinned as the next item for 3.3 but it didn’t;t make the cutoff date. So it will come soon along with some other nice surprises.
