Midi month upgrade not working

[highstandards]

There is a special offer called:
"Celebrate MIDI Month with 50% off Syntronik and Syntronik Deluxe"

I "own" Syntronik and the Syntronik Deluxe Upgrade is at $/€49.99. Great!

I click on the link and I'm only offered the crossgrade...

The eligibility check shows that to get the Syntronik Deluxe Upgrade, you simply need to be a registered user of Syntronik, which I am.

Please fix the shop.
I email the shop last week, but got no news.

Hey highstandards!

Thanks for joining the IK community.

Looking at your account, I see the original Syntronik serial number in your account is a promotional item. This was granted with your UNO Synth from our double up promotion. Unfortunately, this promotional item will not unlock the upgrade pricing for you.

Please feel free to utilize the Crossgrade pricing and use Jam Points to bring this price even furhter down.

A shame, but I understand.
Thank you Ryan.
