Projects with name differentiating only by uppercase are merged together

When I have two projects with name differentiating only by uppercase fist letter, they are merged together into one with the lowercase name.
For example i made project named mortgages and created an asset. Then I imported example project named Mortgages with first letter being uppercase. These project have been merged together. On file system in .niogit I can still see both folders: morgages.git and Mortgages.git.
