How do I redeem all 4 Synty Education Assets

I first enrolled in the Unity student plan in 2022, when there was only one asset we could claim as students—the Synty City Pack. Now, there are three more assets. I had to reenroll today in the Unity Student plan. The email I got told me to claim my free assets. When I clicked that button, it took me to my asset story library but didn’t give me the additional assets I couldn’t claim when I first enrolled.

How am I able to get these free assets? Has anyone ran into this same issue?
