I have a template that includes multiple copies of the same layout, each with a different background picture. This is the only difference between the layouts.
The layout has four text placeholders on it for name, title, date and confidentiality level.
When I create a slide from one of the layouts, populate all 4 placeholders with text and then switch the layout to one of the others, everything is fine.
But, if I delete the text from one of the placeholders before switching the layout to another, the text in the placeholders (PH) rotates. What I mean is that the text from PH1 ends up in PH2, PH2 ends up in PH3 etc. The placeholders stay where they are but the text gets moved!!!
Interestingly, the names of the placeholders in the Selection Pane don't change in the first case but they do in the second so is PowerPoint doing something special to recreate the placeholders during the switching process before pasting the text back into them and thereby messing up the order?
But the big question is "how can I stop this effect from happening?"
I can reproduce in 2013, 2010, 2007 but I haven't uploaded a template as it's a confidential project (I will try to recreate with a new blank file).
