Maybe, like myself, someone else faces the same problem after 7 years… ☺
It’s really annoying, I still did not find any solution for same problem in Adobe Premiere Pro CC 2018
So I needed to figure it out myself:
1: Exit the program
2: Search for your settings file, my default location: C:\Users\username\Documents\Adobe\Premiere Pro\12.0\Profile-username\Adobe Premiere Pro Prefs
3: Open this file with a text editor like Notepad++ my favourite
4: Search for this: Constant Power
5: Change “Constant Power” to “false”, so the line looks like this:
false
6: save the file, start the program and you’re done.
