Creating my own layouts

[Pey1]

Hello friends,
Im trying to create my own layout in PowerPoint. In the Slide master > Placeholder > Text. Im creating a text box with a few bullet Points - a list. But when I Close the master view and get to the normal view, only the first line of my list stays.
I know that eventually this text is just a placeholder text, until the real text will come instead of it, but I Need to see the whole Thing. Any ideas?

*I uploaded a screenshot to helo explain whats going on.

Thanks a lot,
Pey
