There’s no such thing like stem merging. Either we have different 
voices, then they should be discernible as such by having separate 
stems, or we have only one voice, then the chord has only one stem. 
There are cases where two stems are printed on top of each other, but 
that’s a collision resulting from (probably) wrong input and no merging.
I hope you have made yourself familiar with the Learning Manual already; 
if so, there’s further information in
