Armor bug (Fallout 4)

I'm collecting power armor, I have such a weakness. I find them all over the world and bring them to my base. I have already collected 5 pieces and then I will improve. But recently I found a power armor near a building next to which a black security robot is launched through the terminal. So next to this place I found a armor, drove it to my garage and her left arm and leg were broken, I took them off and then repaired them in the workshop and I can't put them on the armor, I write what needs to be repaired first. Although they are repaired. maybe this is a bug or am I doing something wrong? that is, it turns out that I have a left arm and a leg have already been repaired, but I can’t put it on armor, I can’t write what needs to be repaired
