I've noticed recently that wines which we get under the hashgacha of the Bada"tz Beit Yosef list "R' Ovadia Yosef Shlit"a." As R' Ovadia died more than a year ago and these are young wines, I suspect that they were bottled and stamped with his hechsher after his death.
Considering this, is it improper to maintain a hashgacha stamp which lists a rav who is deceased with the honorific of "shlit"a"?
