I did it for you.

All the required tags are in the relation.

You need to delete the tags you added to the way.

Hi
What's the purpose of all these boundary=landuse ways?

way/23949967

Hi again
This entity is a multipolygon relation. All tags relating to the relation should be in the relation.

landuse=farmland is in the relation
boundary=landuse isn't required

Have a read of the Usage section:

osm.wiki/Relation:multipolygon#Usage

Only if it exists & is visible.

Hi
All National Railway railway stations are mapped. Please don't duplicate.

Hi
Duplication leads to confusion & errors. railway:ref isn't specific, it's not clear.
Before I co-ordinated UK stations there was a half-arsed incoherent mess. All stations are now consistently labelled. If ORM want to make use of them they can write the code to suit. The 'rail enthusiasts' who designed the tagging scheme went for extraordinary detail but forgot about clarity. Refs for stations are a combination of namespace & underscore, 'ref' at the beginning, 'ref' at the ends. No coordination.

All national Rail stations have the three letter code using ref:crs. Please don't duplicate

Hi
All National Railway railway stations are mapped. Please don't duplicate them in train station buildings. Tag the buildings as building=train_station.
