I tried changing the category of part of the road and now it's not
merged. Original road had 335 nodes and 50.41 km. I split a portion of
83 nodes/13.26km where I had the problem in the route calculation and
now this portion works fine, but the problem has moved to the remaining
one. Note number of nodes is approximative, as gpsmapedit gives a
different number depending on the zoom level.

What do you mean by "routing nodes"? Are they nodes where to ways connect?
