Embed link from PDF not opening a new PDF file

LATEST UPDAT

(UPDATE)<br>

This is how Opera and Google Chrome show my URL after I click a button in the PDF, which opens a PDF file. <br>
//example.azurewebsites.net/CANGC/Process/off-site-facility-management/6_1-Chemistry/Step-Descriptions/6-1-1/6-1-1-1.pdf

This is how Edge shows the URL after the click, which cannot locate the file.

//example.azurewebsites.net/CANGC/Process/off-site-facility-management/6_1-Chemistry/Flow-Chart/6.1%20Ultrasonic%20Chemistry%20Management/2.%20Process%20Design/2b.%20Step%20Descriptions/1%20-%20Chemical%20Inventory/6-1-1-1.pdf

Edge rewrote the URL longer, forcing the path wrong.

What's funny is that I put the same URL into the Edge Browser, which opens that PDF file. The extensions do not solve my problem. Is there another solution out there?

(UPDATE)
OPERA, FIREFOX, CHROME display my URL path this way:
Process/environmental-health-and-safety/3_3-Safety/Step-Descriptions/1-Process-Improvements/3-3-1-6.pdf

IE EDGE
Process/environmental-health-and-safety/3_3-Safety/Flow-Chart/3.3%20Safety/2.%20Process%20Design/2b.%20Step%20Descriptions/1%20-%20Process%20Improvements/3-3-1-6.pdf

Why is IE Edge ignores hyphens?

NOTE: My PDF file can open the link in Google Chrome and Opera, not Edge. Any help is appreciated. 

My link is relative path. Do I need to put the URL like http://example.com/open-one.pdf?
