Items deleted when connecting 2 boards

Let’s say I´m in board A which has a connected board column.

If I select an item from de connected board column (linked to board B) and then I refresh the page or go back and forth to another board, when I go back to board A, the item i just created/updated with de connected item in board B is gone!!

I’ve done this several times but can’t figure out how to connect boards without loosing information.


Now that some time has passed, refresh the boards that seem to have the items deleted. Are the “deleted” items back now?
