How to always display SLA after stop condition met

[Glen Cochrane]

I have a few custom SLAs to identify bottlenecks in a process but the SLAs on an issue seem to disappear after a Stop Condition is met.

Eg.

Start counting time when... Assignee: From Unassigned

No pause conditions

Stop counting time when... Enters status Waiting for approval

When the issue enters status Waiting for approval or any status later in the workflow, the time cumulated disappears.

Similarly, 

Start counting time when... Enters status Waiting for approval

No pause conditions

Stop counting time when... Leaves status Waiting for approval

When the issue leaves status Waiting for approval, the SLA is no longer displayed/saved.

Is this a crazy assumption that this should work for reporting etc?
