Missing apply / join buttons subspace / subsubspaces

Describe the bug A clear and concise description of what the bug is.

To Reproduce Steps to reproduce the behavior:

1. Go to https://sandbox-alkem.io/alkemio/challenges/raisingthealkemio-6086 with a space member
2. Try to apply / join - no such buttons

When Space has "application not required", "application required" option set, user see "Application not enabled" option. The same button is visible when user is already a member.
