You didn’t say whether it is the main oven door or bottom oven door hinges you replaced. But either way the only thoughts that spring to mind are that perhaps they are not fully located correctly into their sockets? Locking the hinges, removing and relocating the door fully may just resolve the issue….hopefully?
I am not aware of any known problems with hinges except fair wear & tear over time. Having fitted new hinges 2 months ago rules that problem right out I would think! 🙂
