Asset not updated when a npm package is republished

I have a npm hosted repository with a deployment policy = "Allow redeploy" in order to simulate snapshot versions.
After the second publish, I can't install the dependency anymore because there is a failure when checksums are compared (tested with npm 5.6.0 and yarn 1.3.2).
 
The problem appears in Nexus 3.7.0. I don't have this problem with Nexus 3.6.2. 
 
Steps to reproduce the problem:

• Create a npm hosted repository with a deployment policy = "Allow redeploy"
• Create a directory with only this package.json:

{
    "name": "test-publish",
    "version": "1.1.0"
}

• Publish to the npm hosted repository

npm publish --registry http://localhost:8081/repository/npm-snapshots

• Create a file README.md
• Publish again to the npm hosted repository
• At this step, you can already see there is a problem in the Nexus UI (asset not updated)
• Create another directory with only this package.json:

{
    "name": "test-install",
    "version": "1.1.0",
    "dependencies": {
        "test-publish": "1.1.0"
    }
}

• Get the dependencies

npm install

• It fails
