I checked your settings and I was able to replicate your issue. When a notification is sent to your email address only the label or the text of the file is provided - not a link to the file. I tried the multiple upload feature for that same field but the results differ in the sense that a link was provided to the files uploaded.
You can activate the multiple upload feature by clicking the Multiple Upload button on the taskbar once a single upload field is selected. Rather than using 4 different upload fields, this single field option can be explored.
I hope this helps. Do let us know if further assistance is needed.
I have moved your question to separate thread and we will provide you an answer there shortly.
