If you want a Bmaj7 there, it should be written exactly that way. It looks from your post as though you are writing it as "Bm", and that will give you a B-minor chord.

Also, if you are using "Realtracks" as opposed to "midi tracks", then some styles might not contain realtracks with all possible chord changes. This is of course because realtracks are actual recorded clips of someone playing the instrument. If this is the case you might want to experiment with a different style to see if it will supply you the chord change where you want it to be.
