XPath doesnt seem to work.

[Shamatix]

I stumbled upon the SelectorLib and saw you were a contributor so I am reaching out in hope you can help me.

I am having a very hard time getting the "XPath" to work.
I am trying to scrape the following website:

And I am trying to get the following information out.

I have multiple different XPaths that works if I am not using the Chrome SelectorLib plugin, however they dont seem to work in the plugin?

For example:
//strong[text()="Alcohol: "]/following-sibling::text()[1]

or
//html/body/div[6]/div/div[2]/div[2]/div[2]//strong[text()="Alcohol: "]/following-sibling::text()[1]

Both works in the developer tools, but not in the SelectorLib plugin.
