Sandisk DUAL 64GB USB drive read only on android via OTG

I have an issue with this stick at the moment, it’s formated as a 64 GB NTFS partition and i’m trying to write to the drive from android 5.0.

I can read find but when I try and write it comes up with unsupport action in ES File Explorer.

Another USB stick which is 16 GB and formated as FAT32 works fine however.

Any suggestions as to why this is happening?
