[issue] There are no save sets on this volume, but used space isn't release.

Hi, Everybody:

 

I have a problem.

There are no save sets, but  used space is not release.

How to solve the issue?

 

I try the KB(How to manually delete save sets which are within retention period and no longer needed?), but it doesn't work.

 

Thanks!!!
