Import sequence doesn't work.

I am trying to figure out why the "Import Image Sequence" box is greyed out and cannot be ticket. I'm going to get all the basic stuff out of the way. Not trying to be rude, but I've been scrolling through endlessly useless posts that all regurgitate the same basic trouble shooting issues. So here's my situation, if anything you're going to suggest is on this list, you're not going to helpful so please don't rehash stuff I've already read on other threads. Trust me, I have tried, and they have not work:

- The file format I am using is in DPX

- The file names are all numeric and sequential. There are no special characters used in the file name. Just numbers. They all adhere to a four character file name structure.

- I have uninstalled and reinstalled the current version of Adobe Premiere via the Creative Cloud app. 

- When I uninstalled the program I also used Bulk Uninstaller to remove all traces of Premiere from my system. This includeded all registry entries, config files, everything.

- Rebooted my machine after uninstalling and again after my reinstall. 

So if you have any outside of these trouble shooting issues would be greatly appreciated.
