License for Multisite

Sorry for being a pain and thank you for giving me an extra license for a staging environment. I ran into an issue with the staging website.  It is a multisite with 8 subsites.  After I registered Clean Education Pro theme with my key, I checked the subsites and get the following message:

The theme has been successfully activated, but we couldn’t find a valid license key.

I tried using the same key without success.  Any way to fix this? Thinking about my process, I may have activated the license before I enabled "WP_ALLOW_MULTISITE". Thank you in advance and have a great weekend. Sincerely, wcmaster
