This little patch fixes it for me:

Are component and node names case-sensitive in LISO?

Two component names differing only by case -- seems to work but issues a warning "name is already used, this may cause confusion"
Two node names differing only by case -- issues a warning "several pointers to same location" and gives the wrong result
