Received PGWP of less than 2 years after PhD

[amrvx4]

I recently received a PGWP which will expire in 1 year and 10 months. I completed my PhD which lasted about 6 years. My passport isn't expiring as well. Is there any way I could confirm why I have got this short PGWP?
My BVL is expiring by the end of 2026 but PGWP is valid till January 10, 2026
