Help! Little rods and curve rods|

Good evening, I have some problems with this building, I noticed this when I looked at the deformation. The first is the presence of these little rotating rods which I do not think I have included in the model. The second problem is that this rod deforms in this curved way. When I use another structural analysis software, it shows me nodes that I don’t think I’ve included, which are at the end of these little rods. Can you solve the problem?

Hi, thank you for your help, when i prove to remove the dublicate lines it doesn’t work, because the lines are not the same. If i prove to cancel the FL1, FL2 and Frame i’have other problems in the analysys. you can try it on my model, maybe you can do better? Thank you so much
