Premiumpress Multisite

I am facing an issue in setting up multi-site.

My link is http://www.stealdealsusa.com
Subdomain https://shop.stealdealsusa.com

For the first link I am using Responsive Coupon Theme with a Premiumpress Child Theme.

For the sub-domain I wanted to use Responsive Shopping Theme with another child theme.

First site is working fine. The second site also is fine when it is on the main theme. But when the child theme is enabled the link doesn’t work. It says the child theme is of ‘Responsive Coupon Theme’. But the fact is the child theme is of ‘Responsive Shopping Theme’

Any suggestions would be highly appreciated.

Thank you
