Change frame size in Premiere CS4

I have a project with several sequences. Somehow one of the sequences is sized to 432 X 288. I can't figure out how. When I create a new one I can't seem to mimic the same settings for my other sequences, I can't set it to be the size of the other, it doesn't let you choose a custom size. I have no Idea how the first sequence got to be 432 X 288 anyway. So now the two sequences are different sizes.

Below are images of the settings of the two sequences.

I need to know how to get them the same size, preferably the size of the first one.
