This is due to a wrong function call to teitext:getLabel($doc) instead of teitext:getLabel($doc, $edition). Which makes me wonder why this call submits the edition id in the first place as teitext:getLabelonly uses this to get the edition language. There should be a more elegant way for getting language in place.
