SendBetterEmail - Lightning Template Detection of ID vs Name

[Molly-Chicago]

Steps to reproduce

I am using SendBetterEmail to send an email template to campaign members of a campaign. When the Template ID is specified (only), a message is received stating that both the ID and Name have been entered.

When I remove the ID and enter just the name, a message is received that the ID is invalid. I'm not sure which ID it refers to, but all other IDs have been verified.
