Sorry for my English.
Faced with a problem when updating components. Some sites are free components, and some are paid, and should remain.
Before upgrading, I put a checkmark in the desired site and then click on "Download and Install". As a result, the components are updated on absolutely all the sites I chose independently or not.
I use Securitycheck Pro Control Center 1.1.13 and Joomla 3.6.5
