"It should be marked as disputed"

That's not how international law works. By all means maps may be tailored to suit the preferences of markets/countries, but military conquest of a territory doesn't convert it to a "disputed" status. Currently the internationally-recognised borders between Ukraine/Russia are well-defined.

Both Russia and Ukraine claim the territory of Crimea, and it is therefore disputed.

Many territories are disputed without conflict. If military conquest, occupation and de facto control of a territory doesn't reify a dispute, then nothing does.
