We use a Butler command to copy cards from a template board to our working projects board. Last week, things were working great! Today, I noticed that the new copied cards have a different icon in the upper left corner by the card title and there's no "Due Date" option listed on the right menu.
Here's a card copied through our command last week:

Here's a card copied through our command this week:

I do see that the new icon in the upper left looks identical to the "Make Template" icon. We haven't assigned the card on our Template board as an actual Template card - so on the Butler copy, these cards should just be normal cards.
Any ideas why the "Due Date" field would go missing?
