How to clear saved game when using shipping build configuration?

I use shipping build configuration and package my project.When i play game for the first time,i find the best score is not zero.And it is the best score that i ever got.
When i use Developmet build configuration and package my project,the score is zero.
I have tried to delete the .sav file in the project folder,but it still doesn’t work when i use shipping build configuration.
So how to solve it?

Same issue here, did you ever figure it out?
