Document edit creates a new session after clicking on specific menues

here is the effect:
double session

i clicked 3 times more and I got this result:
multiple sessions

even after closing the document and opening up later (e.g. 3hours) the sessions stay.

I also get the effect when the connection times ou but Iā€™m still on the file. Which is anoying if you coorporate on a single xml file.

Is there a way to cleanup or close these sessions?
