Due to your dodgy mapping OSMand was trying to sen me on a long diversion as you have rendered Aston by Stone Crossing un-routable by your addition of lift gates (tagging for the renderer?).
Please don't do that, level crossing barriers are mapped as and attribute to the level crossing. Please see https://wiki.openstreetmap.org/wiki/Tag:railway=level%20crossing?uselang=en
Also the crossing tag you have added is for pedestrians to cross the road, not a railway crossing. This is a mistake I would expect from a beginner.
