On each property listing under the map section, there is a feature that shows Nearest Stations. See the screenshot below for reference:

Train, tram, and cable car stations on property listings are shown "as the crow flies," meaning distances are measured in a straight line rather than following roads or paths.
If you believe the nearest station on the property advertisement is showing incorrectly, we'd recommend first checking the property pin is in the correct location, as this may be why the wrong stations are showing.
If the pin of the property is correct, you can send an email to our Customer Support team using the email: Customersupport@rightmove.co.uk.
It is important to note that there isn't a way to amend the train stations in Rightmove Plus or by your Software system, and there isn't a way that the stations feature can be turned off on a property listing.
