Hi Raymond,
unfortunately, the screenshot you attached is very small and I can hardly read the settings (i've also tried to download and zoom but didn't help).
Would you mind sharing the screenshots again? You can attach each image by its own.
The request itself looks like it wasn't open from the manager as some details in the header are missing (like current stage information). Did the assigned approver open the access request from his work inbox? Can you show us the audit log as well.
Thanks and regards,
Alessandro
