These two carts both use the connections of the rail block under them to determine which way they are going. This system was dependent on the fact that straight tracks could still have different connections despite being the same block, which has evidently been changed with the new block families. This means that these carts only work going in one direction now. To avoid more issues, it would probably be best to use a different way of detecting the cart's direction.
