LODs are swapped

Hi everyone, so I have created a main object and 1 LOD to it. Exported it as a group to UE5. Everything worked fine, but later I had to do some texture changes with the main file.

After that, when I tried to export everything again, and now my main object is LOD and only shown when I go away on a certain distance. And my LOD is the main object. How do I change everything back to normal? I tried pairing objects to empty in different orders but nothing helped
