We are aware of the errors and issues that Lois is currently having and our GIS group is working on a solution for it. We currently do not have a timeframe from them when this issue will be resolved. As a workaround, you should still be able to search for and select specific data (monument name/LPN) using the buttons at the top of the map or navigating the map and selecting the desired data. Then you can export the data to a .csv file using the button in the upper left of where the data would normally display.
