From Enterprise to Standard enrollment

Our company had Apple Developer Enterprise Program and it expired some time ago. Now we want to enroll in Apple Develop Program, but we cannot figure out the way to do it.

p.s. We tried to use this page, but it shows an error "Sorry, you can’t enroll at this time. Your Apple ID is already associated with the Account Holder of a membership." https://developer.apple.com/programs/enroll/
