“Vibration damper” defective on the front axle ???

Hello people ! I’m new here and I have a concern at the moment. I acquired the first Mazda in my life. A 6 Sport Kombi 1.8 GG1 from 2006. Before buying at the DEKRA on stage from below. I only got a fresh TÜV in April. Now in August we found out that this round thing (red arrow) is loose. Like a bushing with rubber. At the front axle on the crossbar left. The DEKRA man said this was a vibration damper and no problem I hope that one of the professionals can help us. Otherwise I still have to be friendly. I am looking forward to the puzzle solution 😉 Greetings to all
