Hello WWMapper101, DWG here. Thank you for involving us (Ticket#2025022110000507). Archie is right, the validator might hint at potential issues but its suggestions should never be followed blindly. Always cross-check with aerial imagery - else you risk adding "crossing:markings=no" to a crossing that is wrongly tagged as "unmarked"! 

(Also, adding "crossing:markings=no" to a "crossing=unmarked" adds zero information, it unnecessarily adds a new version and increases our history database. It's ok to choose the "new" tagging when you add a new crossing, but going over all existing crossings and "fixing" them is of little use.)
