Pseudo box sets

I have some sets that consist of a collection of single albums. To save display space I have boxed them

Take for example Dvorak Symphonies by Jarvi. There is a box set but it’s a different order from the single albums. The upshot is that Roon is failing to identify the compositions

I have six versions of the ninth symphony. In compositions only 2 show up

After manual input etc , splitting discs off boxes and re identifying the Album, it comes right , I have about 40k classical tracks . I simply cannot manually check that each ones has identified properly

The upshot is that Composition is unreliable for me

Any thoughts , its rather frustrating
