Inconsistent file accessibility across public gateways

Hi,
I’m trying to setup an ipfs node with kubo in AWS EC2 instance. While uploading 10 files one by one through ipfs cli, I noticed that only three of them are accessible via the ipfs.io public gateway, whereas all 10 files are accessible through the gateway.pinata.cloud and cloudflare-ipfs.com public gateways.

It’s really inconsistent, can anyone please help me resolve this issue.
