This tab will show all the tracks that Amarok has found in more than one collection, and reflects conflicts. When tracks are grouped, you can see two types of background: light green, and light red. A light green background indicates the new or updated field, whilst a light red background will indicate the old/overwritten field. You do not need to solve all conflicts listed here; the particular field of the listed tracks are not going to be synced if you do not resolve the conflict.
