How do I position these correctly?

I hope someone knows this problem, i'm using a Panel, and Within that panel, I have buttons which make things visible, and invisible. And often when I click to make them visible, they are all being placed wrong.

This is what it's suppose to look like when I click the Yes button, it displays the arrows etc to the right.


Once I run the prorgam it displays each of them further down.

I'm sure this has nothing to do with the code, as the buttons only make them visible and invisible.

Does anyone know as to why this is? :(



UPDATE:

It's now overlapping them with others :s
