Files fail to update through FTP

I changed some of the files in my site through FileZilla FTP, and I check them in it now and they’re gone, and the changes I made are reverted; however, when I go to edit them, the changes aren’t saved. I created a file which is no longer visible inside the FTP client but is accessible through the URL page and the file i edited is still the same as the previous one.

Try after some time…as developers are working on this to fix this soon!!!
