Please Help! Team Base Damage

Hi, I’m new to UEFN and I’m having a small issue with my team bases. I want to prevent the Blue team from damaging their own base, and likewise for the Red team. I’ve looked everywhere, I haven’t been able to achieve the desired outcome. When I start a session through UEFN, I’m placed in the Blue team, yet my walls still sustain damage when I shoot at them. Any assistance on this matter would be greatly welcomed.
