Marketplace L-500 when quantity is above 32bit integer.

marketplace Item with id "9c22e11c-c2ea-4545-bc9f-4433cc621495" has its quantity value set to something higher than the 32bit integer limit. 

response from the api:

https://store.mktpl.minecraft-services.net/api/v1.0/layout/pages/MultiItemPage_StoreRoot

The api has nothing that handles quantities above the 32bit integer limit by for example ignoring the error, or when anything is higher than the highest allowed value, it should be set back to a value that's allowed. Does anyone know how to lower the value again? My marketplace does not load at all anymore and I wanted to buy some items.
