Lip folding and curling upwards up after gummy smile dysport? (photo)

Hi everyone, thanks in advance for your inrerest and help. I've previously had 1 unit of botox for a gummy smile which worked well. Recently however I was convinced to try dysport, the units are different and I was given the equivalent of 1 botox unit, at my 'review' visit I reported that my lip was doing this strange 'folding up' sort of thing when I smile. I want sure if it was too little, too much or the placement. They put another unit (equivalent to 1 botox in) yet still the same?
