issue has occurred when publishing customizations

Hi all,

we have 3 tenants in our erp instance as below.

1. Company (prod)
2. uat2
3. test instance

out of these three, company tenant is being used as the production while other two tenants for testing purposes. Normally, We do our customizations into uat2 tenant, after testing and if it is ok, we publish the customizations into multiple tenants from uat2 to be applied them in the other tenants as well. We have done some customizations recently only for the uat2 tenant, but never published it to other tenants. However, without publishing from uat2 to all tenants, some of customizations have been applied in the company tenant as well. The issue is how it can be happened without giving ‘publish into multiple tenants’ from uat2? Can someone provide me a solution on this?

Thank you.
