train and test xml files are empty (contain no coordinate points)

[jmorr-is]

python3 preprocessing.py -i A_aurata_wings -t aurata_wings_landmarks.xml

After using the above code, the package split my images and landmarks into train and test folders and xml files, but the xml files that it returned were completely empty (didn't contain any of the coordinates that were in the original landmark file "aurata_wings_landmarks.xml").

I used the imglab web browser to create and save these landmarks as xml and pts files originally. Both file types led to the same issue and even when I converted the pts file to csv the problem persisted still.
