Chord symbols don't play, converting from tab to notation
Add chords to a bass guitar tab. They don't play. Then convert tab to notation (using Edit/Instruments then change stave to standard). The chords still don't sound. Open a new score, copy from the previous and now the chords play.
I'm attaching the tab version with a few chords added. (The chords don't sound - and also don't if you convert the score to standard notation). I'm also attaching a score created new with the first four bars copied from the converted tab - this time the chords sound when played.
