Delay between backups on SQL Backup Pro

I see a delay in my backup logs of five minutes. I have 150 small databases to backup. The actual backup takes less than a minute, bu then it's another five minutes between when the next backup begins. Why is this?

I setup a job on another one of my servers that has a similar number of databases, and there is no delay between backups.

The log isn't giving me any insight in why this would be.

Thanks!
