wrong number of metrics in output during update

I've tried to update service copied by toolbox. It shows wrong number of metrics in output:

...
target service has 3 metrics
created 1 metrics on the target service
...

Number 3 is wrong because source service has 4 metrics and destination service has 2 metrics.
Number 1 is wrong because source service has 4 metrics and destination service has 2 metrics.
