I have never seen anything like this ever.  I have files straight out of my camera  with names like "006. 007, 008 etc". I then load them into Vegas but then decide I want to change the names to better reflect what the video is about.  So I close Vegas, change the names in the windows environment. Then I go back to Vegas 19 and for unknown reason it still shows the numbers and not the new file names.  I check back in the windows environment and confirm that I actually did change the files names. So Windows 10 recognizes the change but Vegas 10 does not. Also on my computer is Vegas 16.  I try this same procedure with 16 and it recognizes the change. I tried an entire new project with 19 as well as reboot the computer. How do I get Vegas pro to recognize the new file names?
