Thread:Support/Wikidata links missing on Welsh wikipedia

The link add links on wikibase_client is not appearing on Welsh Wikipedia sidebar, for example on Trawsnewidiad_y_Frythoneg_i'r_Gymraeg. Also, there is no "edit link" appearing under the list of languages if there is only one language linked, for example Hanes y Gymraeg. Do we need to amend our sidebar locally on Welsh wikipedia to get these to appear. If so, how do we do this?
