Some segmentation polygons are shifted after applying data augmentations

Hi. After applying augmentation I noticed that some segmentation masks in my dataset are shifted. What could I do with that?

My dataset is public and here is the link: Sign in to Roboflow

You can preview images in this specific version and find shifted masks. One example is the image with name " PostBarcode016.jpg".

Thank you for attention. I would really appreciate if you would help to figure out why this is happening

Hi @leo

After having a closer look it appears that the problem comes from “shear” augmentation. I have two versions of the dataset: with shear and without it. The difference is visible in images preview.

I hope this link is publicly available: barcodes Instance Segmentation Dataset by project-4nztg

Thank you for your attention!
