This is going to be hard to explain!
I have created a template in 2008 Mac. I have 2 masters, for simplicity I will call them 'Text' master, with various layouts, and a 'Dividers' master, again with various layouts.
In normal view in the design ribbon under Slide Layouts I have 2 master 'tags' - Text and Dividers.
I open template save as a pptx and my presentation has just the two master tags in the ribbon as expected. However if i create another presentation and then insert slides from one to another (keeping source formatting) I end up with 4 master tags - Text, Dividers, 1_Text and 1_Dividers.
I want it to just maintain the original 2 'tags'. The funny thing is on another presentation (also taken from the same template) that I had done a previous test on it works as i want it to work i.e. I insert as many other presentations and only the 2 tags are maintained in the ribbon. The only thing I can see that differs with the one that works is that if i go to File, Properties, Summary - next to Template it is blank. All other presentations next to template it has the name of the original template that they were all created from.
If I uncheck keep source formatting the additional tags are not added but all slides will take on the design of the slide that precedes it - so if that happens to be a divider than all slides will come in as a divider layout which again is not what I need.
If anyone can understand this let alone answer it i will be most grateful.
Thanks in advance.
