It’s all about the style settings of the selected slide.
These settings (bullets) are preset in the Text and Content slide style.
The second shape has these settings set by default.
I’m a bit upset by this behavior : when pasting, keeping the style settings from the source, I would expect all the style settings in the target shape to be overridden by the ones of the pasted text.
Is it me who doesn’t get it or is it possible to have OO to evolve ?
Thanks !
