Watermark section of admin config page won't upload an image

-- Joomla version -- : 3.7.5

Hi there good people

Check this out (in circles on attached image)

This is one issue I'd like resolved, but more importantly, when I try to upload a watermark image via the drag and drop option (it just opens the image in the browser and not inserts it to hikashop) and the second option of "Choose File" it shows the image is ready to upload but won't actually upload it.

Thoughts?
