Indeed, the problem looks like it's a problem mapping between a perl array
and TT's scalar and lists.  Basically, when you return the array from your
subroutine that contains only TT can't tell if it's a one element list or
a single scalar.

Things to do:

 Always return a single arrayref from your function.  This way TT knows
 that you mean a list

Alternativly:

 Use the .list virtual method on the return value.  I.e.
 weightLossFeatures.list.  This will force it to be treated as a list.
