There is one more issue with import of Songs from Songbeamer:
Some weird chords are not converted to the format OpenLP is using. So, they appear also in the Main view and stage view, brackets included. You can reproduce this with the song in my former post.
One of those Chords is displayed as [B=m7] (in Songbeamer it is shown as B♮m7). The chord would be two half notes above Am7 and a half note below Cm7.
I think, the problem is the "♮" sign, which in the sng files seems to be converted to "=" I don't know, which notation would be the correct one for OpenLP.
