Loop Browser Preview Sync disappears

Loop Browser Preview syncs loops and follows tempo changes of the arrangement perfectly (it seems regardless to the file tempo metadata), but the sync disappears when double clicking or dragging the loop to the browser. What am I missing here? Couldn’t find a solution by searching the forum.

Seems I managed to fix the problem;
preferences>editing>audio>(tick)convert and copy to project if needed
…don’t exactly know what happens here, since also before this setting the loops that were imported from loop browser were automatically turned into musical mode, but still had incorrect length/tempo.
