Help Unable to rename directory on internal card

[deltaforce]

I rooted my Galaxy S4 Play edition using Chainfire rooting method. All works good, no issues that I can notice. In the past, before rooting, it wouldn't let me delete files on external SD card, which it does now. But it doesn't allow me to rename a folder on internal SD card, via PC or ES3 file explorer.

Anyone can think of the issue? How do I fix this?

Thanks in advance.

Is this all folders, or one particular folder?
