Export not work when using UID context and non-Admin downloads

I have a user specific View (UID by logged in user) and tried adding a data export (CSV) for the view. I gave the export the url: collection/%/csvexport.csv with the only context being the UID. When The admin (or uid 1) downloads, their specific csv works no problem. When another other user tries to download their own list, the CSV will download, but it will not include any data except the field headers (one row, only headers for each column).

I tested this again without the UID and all users could download no problems. I've also made sure to set permissions to None on the data export just for testing (I will want authenticated users only).

I thank you all in advance.
