Rules works sometimes, why?

[MF_BOT]

I have a google spreadsheet that feeds to create a Trello card. The custom fields are auto-populating as I would expect. Once the card arrives on the board I have this rule:

when a card is added to list "Unito Move", set the card's description to "**Type**\n {{%Type}}\n\n **Deliverable**\n {{%Deliverable}}\n\n **Content**\n {{%Content}}\n\n **Sizes**\n {{%Sizes}}\n\n **Digital/Print**\n {{%D-P}}", and add the dark sky "TW" label to the card

Then a Unito rule copies the card to another board once the dark sky "TW" label to the card.

Sometimes the description has the information and sometimes it only has the text items such as **Type** but is missing {{%Type}} information.

Does anyone know why
