Does not replace media reliably

In the past it would never replace on the first go but after two or three goes it would replace. Now it does not replace at all

I have an image that was edited slightly and replaced

It doesn’t really matter what options I choose. The file is not replaced.

It is not a caching issue I opened the FTP and the file has the same date from last week. I download the file from FTP, surely this cannot possibly be a cache of any sort.

I do an image comparison on the file and it is not the file I uploaded. It is the old file
