Simple newbie question.  When I look at the BOM, under the Manufacturer Part column, some parts have a blue shield icon with a check inside it and the tooltip states: "This component is verified".  Some parts don't have this icon.  I don't know the difference between a verified and unverified component.  Nothing about this is stated in the BOM tutorial page ([https://docs.easyeda.com/en/Schematic/Export-BOM/index.html](https://docs.easyeda.com/en/Schematic/Export-BOM/index.html)) nor could I find anything about this with Google or the forums. Are 'verified components' important?  All the parts are selected directly from the LCSC website.  Is there any way on the website to know what parts are 'verified' and which are not?
