Google Places and Google Maps - risks from having 2 different entries?

[Antara]

It is a company website that I'tm working on.

The company was registered under Google Maps and the API was integrated in the site. But there were two problems

1. The pointer was at a wrong location
2. The categories were not really exact

After a few months, I submitted it in Google places providing the correct categories and pinpointing the exact location of the company. But now as I search wth the company name in Google, it shows 2 results in Maps.
Now my question is

Can it give rise to an issue of duplicate listing and attract penalty for the website ?
If so, what would be the possible way out? Should I remove the previous wrong listing in the map and integrate the API of Google places? Or should I remove the listing of Google Places and just make corrections in the Maps ? Or should both stay ?

If Google Maps were to decide that you were attempting to spam up their listings with duplicate entries, it could result in a penalty. With an accident of this sort, I'd expect that there's relatively low chance of them thinking it was purposefully malicious/dishonest. So, it's unlikely to result in a penalty.

However, having duplicate listings for the same business location can result in a loss of potential ranking power, as the ranking signals may get split between multiple listings, instead of adding up to enhance the rankings of a single listing. So, for this reason, you should try to resolve this issue.

I suggest that if you have not claimed and verified ownership of all of the listings appearing in Google Maps, you should do so. Once you're owner-verified, click the "delete" link with the listing in Google Places, and request to remove the listing from Google Maps. It may take a couple of weeks for the remaining listing to take the place of the removed listing in the search results, depending upon all of the information you've used to customize the business information within Google.

Thanks Silvery!
In the meantime I had just edited the listing with Google maps and maintained the same data for both maps and places.
Now as I search with the company name, they show one listing only in Google organic search results. It is when I search in Google Maps, they show 2 listings.
The one is Maps is ranked "A" and the one in places "B". In such a situation, shall I remove the one appearing in Google places ?

I concur w/ Silvery. Keep the one that is more accurate, more updated, and more authoritative.

Thank you all, I just rectified the one in Maps and suspended in Places.
This solved the issue. Now it shows only one listing in Google.
