There is a rectangle with text but footer doesn't move?

Hi,

Please look at this attachment, No 1, 2 pages, the pink texts adding, and footer auto extend,
but no. 3 page, I added a rectangle with text, but why it doesn't move as the pink texts,
how should I solve this situation? and make them auto stretch as the pink texts. Thanks you.

Best,

Alexia
