Help my Civic swims!

Hello, I have a problem with my Civic eg3 and wanted to ask if someone can help me. About a month ago I had the front track rod heads and the carrying joints (ball heads) changed at ATU. After everything had changed, I found that my Civic swims (from about 70 km/h , sometimes it is there, sometimes not, mostly only on smooth roads, not on hexes). The at ATU could not explain this and for days tried the problem with the setting of the After a week and a half I drove the highway and found out that 130 is the highest of the feelings. That was enough for me and I drove to Honda. They told me that it was the track and set it up again, without great success. After that they looked at the work of ATU again and found that the track rod heads have different shape and length -> that must not be. So to ATU, they ordered the parts again and came again two different ones. After a long time back and forth they ordered the original parts from Honda and finally installed them yesterday. I already hoped, but again no luck. The f driving behaviour has improved (130 without problems), but it still floats. At ATU, they also don’t know what to do anymore, want to exchange a parr parts. The tyres and the rims are probably also I really don’t know what to do anymore.
