Hello,
For better understanding the problem you may provide us a screen shot of how the side note appears.
Meanwhile you may manually resize the side note window and check.
To do that, open or create a side note, resize the window by dragging the double ended arrow which appears in the corner of the window, close and re-open the side note again and verify the result.
If the above information does not help, then you may reply for further assistance.
Thank you
