Flexslider Library version not detected

After installing this module and the library, I get the following message on the Status report page:
The FlexSlider library could not be detected. Please consult the README.md for installation instructions.

I'm using composer to get the library with the following in the composer.json file:

{
    ...
    "repositories": [
        {
            "type": "package",
            "package": {
                "name": "woocommerce/flexslider",
                "type": "drupal-library",
                "version": "2.3.0",
                "dist": {
                    "url": "https://github.com/woocommerce/FlexSlider/archive/version/2.3.0.zip",
                    "type": "zip"
                }
            }
        },
    ],
    ...
    "require": {
        ...
        "drupal/flexslider": "^2.0@RC",
        "woocommerce/flexslider": "^2.3"
    },
    ...
}
