visual studio - Why does CodeLens always show "0 authors, 0 changes"?

Question

I have a Visual Studio project/solution in a Git repo. Visual Studio's source control feature works a treat (second screenshot). Thanks "Microsoft Git Provider"

HOWEVER CodeLens shows "0 authors, 0 changes" for every class and method (first screenshot) with tooltip explanations:

no data available for this type
no data available for this method

Any ideas why it could be broken?

More detail: the git repo doesn't have remotes. Visual Studio isn't connected to any Team Foundation server. I'm using the exact version of Git that shipped with Visual Studio 2015 update 1.

>git --version
git version 2.6.2.windows.1

I came across the same issue in VS 2017. The fix was to change "Changes in months" field. If you left click on "0 authors, 0 changes" link, a pop up will appear. It has a field in the bottom right corner which you could adjust. I changed it from 12 months to 48 months. The change was automatically applied to the whole solution.
