API returns invalid data for certain POAP?

Hello, I'm Lemon from Guild we are currently troubleshooting a gating issue with a POAP drop.
the dropped POAP is not visible by the explorer/gallery and users who claimed can't seem to validate they hold this asset because the API returns an empty response.

I created a POAP with the same settings and claimed on my wallet and I can get a response and gate with it.
My POAP id: 100411, theirs: 45588
Why there is no response for theirs? I would guess the private event but it has nothing to do with it.
I'm asking for technical help with the API.

Thanks in advance, Lemon
