Essential Diagram Undo Redo

Essential Diagram is a ver useful product but I''ve noticed what appears to be some very odd behaviour in the undo / redo functionality of the essential diagram controller class - I was wondering if anyone can explain if this is by design? (I''m assuming its not). I''m running the 2109 versions. A simple example of the behaviour is to open the Symbol Designer and create a new symbol. Create any type of shape on the diagram surface, select it and then move it several pixels in any direction. Perform an undo, then a redo and then repeat. Eventually the shape will slide off the diagram. I would only expect the shape to alternate between the two points before the move operation and after the move operation. I''ve also noticed that undo/redo seems to work inconsistently in cut / copy / paste operations using the built-in methods for each, Thanks in advance for responses
