This is probably something to with the order of dimensions in the two
spectra. The propagate function works by collecting resonances for each
type of isotope and then tries to fit these to the target peaks. Now this
is usually done by matching shift values to peak positions within
tolerances.
However, if working with a target that has no representative in a given
shift list the function assigns the resonances to the dimensions in the
same order that they appeared in the source.
If the order of dimensions differs in the two spectra then you get
problems. If the experiments happen to be the same type I could maybe
guess a better equivalency. Predicting equivalency based on shift
similarity is not really an option because you don't know how far shifts
have moved.
