fillPeaks removing groups

Dear all,
I have noticed that my grouped dataset (using the "nearest" method) generally contains more feature groups than the grouped dataset after running the fillPeaks function. I thought perhaps fillPeaks was doing something clever regarding re-grouping, but after inspection, some groups just appear to be gone, and the peaks that were in them are no longer represented in any group, although they are still in the peaklist.
I have checked this by confirming that after nearest grouping, all peaks in the dataset are accounted for in groups, however this is not true following fillPeaks.
Can anyone enlighten me as to what's going on?  Seems like an additional filter, but i can find no information about it on the web or in the xcms documentation.
thanks!
