I have found another bug after all. Since the last update, when the finger tap is set to undo, the last two annotations are always deleted, not just the last one. No matter if stamp, pencil or other annotations. 
In addition, when switching to annotation mode and exiting the mode with the setting "use Single page display Mode" there is always a loading delay with a short black screen for a short time. When "Single page Mode" is deselected entering and exiting the annotations mode works flawlwess.
