Hope you are doing well.
I am unable to replicate the scenario from my tenant. I have tried with the same request body which you have mentioned in the case details and getting reminder details in MS Bookings. Please refer the below screenshots:

Can you please try to replicate the scenario from MS Booking UI, If still you are facing the same issue, it's suggested that you could post your case in dedicated forum for Microsoft Bookings for professional advice.
If you are unable to reprocude the issue from MS Booking UI, I would recommend you to raise a support case with Microsoft Graph, a Support Engineer will be able to assist you better. You can raise support ticket from http://aad.portal.azure.com or https://admin.microsoft.com/#/support/requests.
Hope this helps.
