Calc: Draw Functions

I have added several lines in Calc for a drawing and notes. I save the document and reopen it - lines are moved all over the document. This happens everytime the document is saved and closed. Is there a way to stop the lines from shuffling around?

Is there a way to ‘connect’ a line to another or even to a cell? When adding rows/columns the placed lines do not follow the cell where the end point lays. Anchor does nothing that I can tell.

Using the latest version & Win 8.1
