RPM Package Name is not correct

The Couchbase Server 4.0 RPM names are not correct.
Before installing the RPM package (just after download), I have
couchbase-server-enterprise-4.0.0-centos6.x86_64.rpm for Enterprise RPM
couchbase-server-community-4.0.0-centos6.x86_64.rpm for Community RPM

And after the installation (yum install for example), this is the name of the RPM Package
couchbase-server-4.0.0-4051.x86_64.rpm for Enterprise Package. enterprise and centos6 words are missing
couchbase-server-community-4.0.0-4051.x86_64.rpm for Community Package. centos6 is missing
A internal number (4051) has been added.

It’s the first time that i see a non correct RPM Package name on databases solutions.

Is-it possible to fix this bug ?
