[TYPO3] macina banner placement issue

[Stephan de Bruin]

Hello List,

I want to use the macina_banner extension on my site and I've got it to 
work, but there is something not working right.

When I select an item in the placement tab, it moves neatly to the left 
frame. However, when I save the document, it's not there anymore.

Am I missing something/doing something wrong?

Thanks in advance for your help.

Greetings,
Stephan
