Removed image cannot be added again

[TheUnriashol]

I have implemented this plugin on my website and it works great. I really like the design and the features it offers. The only thing I have noticed, but am not sure if it is an issue on my side or a simple bug.

When I select a file that I want to upload it shows me the small preview at the bottom of the container. I then remove the image by clicking on the small X at the top right of the preview. This removes the image and the preview correctly. But then, if I select the same image again it doesn't show the preview anymore. From what I could figure out it is selecting the image, it just simply isn't showing the preview.

UPDATE: This only happens when using the button to upload. With the drag and drop feature this does not happen.
