editing a card causes all cards to display "{{{Front}}}" instead of text

Normally, and this is still the case with my old decks, when I edit a card, and click "Continue Reviewing", it goes back to displaying the front of the same card.
Today I downloaded two new decks. When I have tried to edit a card in either deck, as soon as I click "Continue Reviewing", the front of every card in the deck now says "{{{Front}}}" (minus the quotes), and the backs "{{{Back}}}". And if I browse cards, they look like that, too, although the edit boxes show the true contents. This isn't fixed by restarting or checking the database (which says ok). As I said, this doesn't happen with my old decks -- they still work fine. The new decks were entitled "GRE Princeton Hit Review" and "GRE High-Frequency words".
One time I noticed a seg fault was reported after quitting, but not the other times I tried repeating this.

Edited to add: I don't actually have to edit the card for this to happen: just clicking the edit icon, and then "Continue Reviewing" is sufficient.

I have hacked around this for now by noticing that the problem doesn't affect decks I create myself. So I took the decks I wanted, exported the cards into text, imported them as new decks, and they are now editable.

is this still an issue ten years later?
