I found a confusion to quickly identify differences between "Preserve scroll position" and "Fixed position when scrolling" looking alike check boxes, and resulting checking a wrong box and then dealing with prototype "glitches", XD agent support, and overall time waste.

I hope XD Design can do something better to visually identifying distinction between these two features/functionalities in XD user interface, such as adding icons to better visualize "fixed position" and "preserve scroll Y-coordinate"
