I suggest a
 zfs list -r -t all void/store
to make really sure we/you see what we want to see.

Can it be that an application has the 23G still open?

The default setting of showing snapshots or not changed somewhere. As
long as you didn't configure the pool to show snapshots (zpool get
listsnapshots <pool>), they are not shown by default.
