Template replaces all instances of Service

When I create a new service using a template, Serverless uses the service name to name the service but it also replaces every instance of “service” in the serverless.yml.

So if I create a new service named test12345, I get this (good):
service: test12345

But I’m using a template which includes an S3 bucket policy,
which includes
PolicyDocument:
Statement:
- Principal:
Service: “ses.amazonaws.com
Problem is, the template replaces this with
PolicyDocument:
Statement:
- Principal:
service: test12345

So this seems to be a bug in the template function. Or not? Is there any way for me to get around this?
