No binlog position from crash recovery is shown after restoring from RDS Aurora snapshot

Hi there, I have been trying to carry out binlog replication between two Aurora databases (the original running aurora5.6, and a restored snapshot of the original that is now running aurora5.7). However, after I restore the snapshot from the original, there is no event stating "Binlog position from crash recovery is binlog-file-name binlog-position" in the Recent Events section in the restored instance. I am following the tutorial shown here https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/AuroraMySQL.Replication.html#AuroraMySQL.Replication.MySQL

I am currently stuck and cannot move forward with the replication due to this. Any help is appreciated, thank you!
