Syndicate Safehouse Agents missing

I managed to remove the final Agents from the Syndicate Safehouse (see Image on Imgur)

Steps to do that:
1. Be in a map
2. Have a Safehouse ready (or nearly ready so when you kill the corresponding agent it will be ready)
3. Have the Safehouse agent on the map and kill him
4. Open the Safehouse portals through Jun
5. Have another agent who will give you intelligence for the agent you have as the "Safehouse agent"
6. While the portals are opening (idk if the timing is important or if it was coincidence) gain intelligence for the "Safehouse agent" through your other agent
7. The Safehouse map has the normal monsters befor the final fight, however there are no agents and the door for the rewards stays closed

Hope this helps in replicating and (hopefully) fixing the bug
