VQA v2.0 40000+ images are missing #18

The number of images on the homepage (https://visualqa.org/download.html ) does not match the ones I'm getting after extracting the files. I'm getting this issue only for balanced real images, not for abstract scenes.

Training Images: Expected 82,783 vs. Actual 41,635
Validation Images: Expected 40,504 vs. Actual 40,493 (close match)
Testing Images: Expected 81,434 vs. Actual 41,915

I didn't receive any error while installing or extracting the zip files, so I don't think there is an issue with file extraction. Is it possible that there is some corrupted data in the file which I might not be aware of? Or maybe the file explorer isn't giving an accurate number (is this possible?). I want to confirm if anyone has faced such an issue before with this dataset, or in general while downloading a huge dataset of images locally.
