Body bends when jacking

I tried to post this earlier, seems it got deleted or something...hmm

I was curious if anyone else has this issue.

I jacked my car up, put stands under the door/frame area. When i let the car down you can see the car bend, the front clip drops...is this normal?
I thought i had bent my car in half when i first saw this..but it straights out...do i need to work?
I do plan on subframing it in the future to fix issues just like this, but this bending mean i have some kinda structural damage already?
