Hello,
(google trad mode)
For the deputies of the Duchy of Savoy in the Parliament of Turin, there is an article in French a list "Deputy of the duchy of Savoy" with the category and I completed on Wikidata with the corresponding elements that I add on the articles.
By adding "Deputy of the Kingdom of Sardinia", this creates a duplicate and empty sections in the infoboxes.
Maybe I created the element "Deputy of the Duchy of Savoy" badly and it should be better linked as a subset of the element "deputy of the Kingdom of Sardinia".
