Incorrect data return in own setup ?

hi,

We setup our own instance of nominatim(version 3.1.0) with planet data (Planet data downloaded on July 1st week 2018 & not yet updating regularly).

The below Nominatim reverse geocode URL return correct data.

https://nominatim.openstreetmap.org/reverse?format=json&lat=19.1896835&lon=72.9465236

But my nominatim server return incorrect result(postalcode only incorrect) as follows:

{"place_id":"1568360","licence":"Data © OpenStreetMap contributors, ODbL 1.0. https:\/\/osm.org\/copyright","osm_type":"way","osm_id":"390034175","lat":"19.18943535","lon":"72.9461104562161","display_name":"MANGAL KARYALAY, Shreenagar Main Rd, Kisan Nagar, ठाणे, Thane, Maharashtra, 560092, India","address":{"townhall":"MANGAL KARYALAY","road":"Shreenagar Main Rd","suburb":"Kisan Nagar","city":"ठाणे","state_district":"Thane","state":"Maharashtra","postcode":"560092","country":"India","country_code":"in"},"boundingbox":["19.1891871","19.1896785","72.9458731","72.9463452"]}

Note: The same data may updated recently(after i have downloaded planet data)? If yes, how to confirm the same. I tried as https://www.openstreetmap.org/api/0.6/way/390034175 . But it shows timestamp as 2 years old.
