Unable to choose an installation profile on a multi-site installation I installed drupal 8 with the open social installation profile using composer. Now I want to turn this drupal install into a multi-site installation where some of the other sites don't use this installation profile. But when creating a new site (I know how to do this from my D6/7 days) I can't select an installation profile. Instead the Open Social installer is always run and it's installation profile always gets applied. 
I figured out it is probably due to the vendor stuff that composer does when installing drupal and open social. It changes some things in the vendor folder that change the drupal 8 installation procedure. But the question that remains is if it is possible to still use this install with the standard drupal installation profiles.

Or a perfectly acceptable alternative for me would be to make a base install of drupal8 and afterwards add the opensocial installation profile so I can still choose my installation profiles. I guess that would mean ditching composer? Or maybe not? I don't really know because I am not familiar with how composer changes the drupal workflow from the way I used to work with it in d6/7.
In the .info.yml file, do no put distribution statement, ss mentioned in this guide:

# Optional: Declare your installation profile as a distribution
# This will make the installer auto-select this installation profile.
# The distribution_name property is used in the installer and other places as
# a label for the software being installed.
distribution:
  name: Distribution Name
