Files disappear when i copy them from external HDD to Macbook

I am using Macbook Pro (13″ mid 2014) and 1TB Lenovo HDD 3.0 (Format: NTFS) My HDD is in NTFS file format and I am using Mounty to access NTFS files. Some of the files appear greyed out and i can’t copy them to my Macbook. I get a popup every-time i try to copy or move such files.enter image description here
