If a tab has the same name as a card, should the card heading be removed?

I am using material design concept. I have tabs and within each tab are cards with headings and content. Sometimes there are 4+ cards inside each tab, sometimes there is only 1 card.

I understand that if there are multiple cards, every card within each tab should have a separate heading.

If there is only 1 card within the tab: does the card need a heading? Or is the name of the tab enough?
