CC-clusters containing N in Albanian

Hello Abdullah,
I couldn't find another bn > m examples but
Alb. lumë/lum `happy, blessed', however I think that we can consider
as the general rule <<labial>>n > m

I.
pn > m (gjumë)

np > ?

bn > m (lumë)

nb > ?

mn > m (dëm < Lat.damnum)

nm > m (emër)

My Question: Abdullah, how you find out that the mn was the
intermediary stage? Based on the preservation of mn in Proto-Romanian?
