New version 13.67 doesn't amplify audios

BoW

I just finished editing a video on an older version and when exporting, I was asked to upgrade to the newest version. When I opened the video in the latest version, I found the sound of the audio files was extremely low, but they were automatically amplified in the older version. I set the "Amplify" under "Audio Effect" but it didn't change a thing. What can I do in the latest version to amplify the audio or is it possible to go back to the older version?

The amplify effect is working normally in 13.67 here. Prior to loading the project, go to OPTIONS | DISK tab and Clear Unused Cache Files.

Also look under the Media tab to confirm that this box is checked...

Older releases are available here. Ignore any virus warnings.
