Basic file upload to update file.

Hi, I have been searching all over for this, but have nto really found anything, so maybe it’s obvious? When we upload images or documents to replace previous versions, our files are instead just renamed (_0, _1, _2, etc.). Is there a way to replace the uploaded files?

Any workarounds?
