PowerShell, posh-git is reporting .gitignore'd folders as being part of the repo

Question

I have a git project spawns a lot of nested sub-folders beside the project (I need the project to be at the root of this folder tree for various reasons). All of these subfolders are in my .gitignore so should have no relationship to my git project. However, when I am in any of those .gitignore'd subfolders of my main project, when I do a dir when the posh-git module is imported, it reports that I am in a git project, and states the number of uncommitted changes in my root project (I'm not talking about being in the .git folder, just normal folders that are within the repo folder, but are also in the .gitignore). I would like this subfolder to not be regarded as part of my git project. Is git-posh reporting this wrongly? i.e. should a subfolder of a git project even if it is in .gitignore be regarded as part of the project?
