Presentation bug -Jumping Objects

[Siebenschläferart]

Hey fellow Designers,

has anyone come across the problem of jumping Objects while in Presentaion Mode? 

I have the problem, that even though an object is located in a certain spot (x: 450 y:450), and i duplicate the page and the object is still in the same spot, that in Presentation mode, it jumps a bit, even though it should be exactly the same? 

Thanks for your help! 

Have a wounderful day 🙂

Btw. It seems to be a Problem within InDesign, because the PDF exported is flauless.
