Chistmas Card - 5th text block missing for customer to edit.

[Mistica]

Been trying to see why the 5th editable text block is now missing for this design collection for the customer.

I tested a few cards from that group...they all did not provide the 5th block. What am I missing here? I know it worked before when I made them. Now they are all useless.

Your above link returns a product-not-found page. Did you mean this one?

I see what you mean though, the last line for family name is not included on the left panel as template text. 
But you can double-click on it from the right side to edit, same as the other text blocks that ARE templates.

I had something similar happen with one design, noticed a month or so ago that one of the text blocks I set as template on a card had disappeared.
