Limit on erc-721 claim page

I’m trying to do a limited drop of erc-721 tokens with a claim page, but apparently it says there’s a limit of 1000 (or I can make it unlimited) I’m wanting to make it a cap of 3K tokens, but it won’t let me.

Is there a way around this? I saw the RealVision drop that happened a few days ago was a limited erc-721 with greater than 1K. Thanks!
