Minor bug: Number of Zones displayed on Iro Settings page

Very minor bug, but in my opinion, the text on the Iro settings page for Zones should indicate how many zones are configured and not the total number of zones in the system.

@bpjones Good catch!

Good find, I seen that and tried to delete the zones not setup .

This was fixed in the latest update mine says 9 of 16 zones used!
