Help needed implementing [[Module:wikipedia]] on [[:af:]]

I am trying to implement Module:wikipedia on af:. E.g. see af:Module:Wikipedia and an example usage of the module on af:A4. At the moment Wikipedia with an interwiki link to w:af:A4 gets printed at the bottom of the box, which is superfluous and which doesn't occur on a similar implementation of the module on the English Wiktionary (cf. the). Are you able to assist?
