Re-uniting split albums

Hi I’m only like 2 hours with Roon !
After the first "Awe " for the performance now I’d like to mend some problems that I found
like split albums - how do I get them together / re- unite them in ?

As stated by Rugby in a similar post: “Under Album, hit the Edit pencil and then go to Fix Track Grouping”. You then search for the missing tracks (by using artist or album name or composer, etc.) and add them to the tracks you currently have in the album by using the right arrow icon. Save the resulting tracks and album should be fully re-built (and if lucky identified).

Thanks a lot !
First thing I learned !
But there are more so … ill keep asking
