Hello,

When checking the challenge for https://trailhead.salesforce.com/trails/force_com_admin_intermediate/modules/business_process_automation/units/process_builder, I receive the message "Challenge Not yet complete... here's what's wrong: An update to an account record failed to update the mailing address fields of all child contact records. Make sure that the process is correct and that it is activated." My process is active, and as I have only 12 accounts and 20 contacts in my org, I have updated the Shipping address of each Account and verified that all corresponding Contact mailing addresses are updated as expected by the process. I have no orphan contacts, and no accounts with zero contacts. Any idea why i would receive this error?
