WFLW Ground Truth landmark coordinates doubts

[cassie101]

Hi @wywu, we noticed that some of the points for testing are strangely labeled. For example, in image 20_Family_Group_Family_Group_20_118.jpg, the landmark for point 88 (left inner lips) and 92 (right inner lips) are labelled at the same location.
In your ground truth, this corresponds to element 176,177 and element 184,185 which coordinates are:
'511.903015' '176.186005'
'512.805786' '176.284866'

Are they done intentionally?
