Why node level data page is not fetching the results correctly in Prod?

This was asked in an interview, In node level data page earlier i was getting 10 records fetched now after a change i want 11 records to be fetched but 11th record is not getting fetched in production why?Can someone please explain the reason behind this?

Hi @TanyaS58: Possible chances - The data page is still not yet stale to reload / application pointed to the access group configured to the node level data page is not having latest changes.

Thanks.
