Different ages on different pages

Hi – the plugin has worked great for my client for a year. However he now needs two different pages to have two different ages. The plugin seems to be set up nicely to do this using [aoage] in messaging, but then on my individual page, if I set the age gate value to 21, that page still pops up displaying my minimum age value that I set on the global settings page (which is a required value).

In other words, my global value of 18 is the only age I can get to pop, even on pages set to 21. What am I doing wrong?

I just disabled all plugins except yours and went to 2015 theme and the same problem is happening.

Please advise

Thank you
