Theres a formatting problem at the foot of the wiki

I only have one wiki and am creating branches for it.

For my wiki it makes sense to have overlapping wiki categories. So one post might be in the
category for the type of boat plan,
also in the category for the part of the boat and
a third category for the subpart.

At the bottom of each wiki entry is a list of the different categories the post is under.

They are not spaced correctly because no spaces are in the formatting
They look like this...

Category: centreboardfoil accuracyFoil sectionfoilsrudder
? PreviousNext ?

It should look like this (I've added commas to make it clear, but spaces would be adequate.
centreboard, foil accuracy, Foil section, foils rudder
