What happened to the Exam Preparation Guide for some of the other certifications?

Hello,

For some reason, under `certmetrics.com/adobe/candidate/exam_scheduling`, I am unable to find information pages (express adobe) for the other certifications such as AD0-E123 or AD0-E129. How do I go about accessing those other pages?

Were those links there before but were removed because they were outdated? Is that the same for the AD0-E132 certification as well?

Regards,

SJ
