Settings form appears on Group config pages

Likely because of the multiple_select.links.task.yml file, with the following:

base_route: 'entity.group.collection'

Not really sure the connection between this module and the group contrib module, is it needed? It might be that we do want this tab on another page, but it'll need a maintainers feedback. Id be tempted to remove it in its current form.

I don't think there is necessarily any relation with Group. I was surprised to find the settings form there.

Yeah indeed, feels as though the intention was for the tab to exist but in a different context.
