FCA and FCF recertification

Hi everybody

Currently, I have an active FCA and FCF certifications, but it is near to expire.

I checked the fortinet training page

In this page, I see this consideration.

• If your FCA certification is still active, you can extend its expiration date to two years from the date you complete one of the following requirements:
• Completing the FortiGate Operator course and passing the FortiGate Operator exam.
• Passing one exam for any FCP certifications.
• Passing one exam for any FCSS certifications.

However, when I took again the Fortigate Operator exam, I can't recertify. Can help me about it?

How I can recertify the FCA and FCF qie the Fortigate operator course??

Thanks in advance
