Artifacts being written to the wrong AWS S3 directory

I'm trying to take the two artifacts in my Builds folder and publish them to an AWS S3 bucket under the folder ProjectIliad.  Here is my artifact paths.

Builds/ProjectIliad-0.1.%build.counter%-Win64.zip => ProjectIliad
Builds/ProjectIliad-0.1.%build.counter%-OSX64.app.zip => ProjectIliad

It's able to find the two files.  However, it writes them to the directory s3://bucketname/ProjectIliad/ProjectIliad_TheBuild/%build.counter%/ProjectIliad.  How do I get it to just write to s3://bucketname/ProjectIliad?
