If track 6 should be symphony no. 1 - movement 2, then this is easily fixed.
If track 6 is indeed symphony no. 2 - movement 1, then the problem is that Roon finds a common stem immediately after “Prokofiev”. Tony’s suggestions are sensible.
In general, ensuring a good, unambiguous, common stem in the track titles is important. Adding opus and/or recognized catalog numbers is also a good idea.
However, if you don’t have another instance of the composition in your library which has been identified by Roon (i.e. come from Roon metadata), Roon will not, as yet, “identify” a composition (against Roon metadata) from file tag metadata.
