Just reran this tool and it did indeed give me multiple outputs. I
think the problem is the files appear but the history needs to be
refreshed to see them. There is a little refresh icon at the top of
the history panel that is needed. This is a known limitation of the
multiple file output support currently. If the tool outputs pretty
regular homogeneous files, it is probably worth investigating
outputting a collection of files instead of individual files. This way
these files can be used in workflows for instance and operated on as a
group.
