Sometimes can't tell who called the role first

After getting into the normal game's champion selection stage people call their roles and normally who called the lane first will get the position. Problem is sometimes with various reasons two different players both see themselves called the role first. It is very annoying. Before, this error happens but not very often until the new patch arrived. Hope you can look into it and fix this issue or figure out some methods to avoid this situation to happen. Think you for your time.
