Why doesn't the close button always appear in fancybox?

Question

fancyBox

I give one button data-fancybox data-src="#block"and the second data-fancybox data-src="#block2"
difference in the blocks, the first is small for the form, the second is stretched in width by 90% and overflow-y auto is set to it
because there is a lot of text that would scroll vertically

, the problem is that one has a close button on the overlay the second one does not, it is not clear for what reason,
but it is needed
