Why can't I use the Built-in Blocks in SP Page Builder if I have the All-Access license?

Why can't I use the Built-in Blocks in SP Page Builder if I have the All-Access license? When I try to use the Built-in Blocks by adding elements in the Sections Library tab of SP Page Builder, it won't let me because each element has a yellow "Pro" label. My license is active, and the license code is entered in the SP Page Builder settings.
