Workflow Notifications


Hoping someone can help with the below:

For my department's invoicing process, a smartsheet was created with 15 different workflows, one for each vendor. Each entry could require anywhere from 2-6 approvals from management based on the invoice amount.

Recently, some aligned users have been receiving MULTIPLE email notifications requesting approval and some users have been receiving emails notification requesting approvals who do not manage that vendor.

Is there something I need to add to the workflow to have only ONE email notification go out? Workflow doc attached for reference.
