Dublicates listing in Real Estates

Hi,
I am using Current version: 8.3.1. I have installed some plugings such as Real Etates Attributes Plugin,    
Car Attributes Plugin, Products Attributes Plugin and so on, which only Real Etates Attributes Plugin is activated. And I have published two villas, and an olive grove and a bike ads on osclass. When I search "villa" on the home page it lists 4 villa, whereas it should have listed two villas. Doubling the two ads it lists 4 villas. Only search "villa" causes this the other searchs result correct.It is strange. What should have been?

could it be cause by one of plugins?

although I have installed some plugins, none of them are enabled. So I don't think it is due to a plugin. And now, I have just deleted all the plugins, the issue still continues

and are those just 2 listings even you check by id right?
in such case I would recommend to try to recreate them, you might get something duplicated somewhere

Osclass is installed on localhost for testing purposes, and there are only 4 listings. Two of them are for two different villas, and the others are a bicycle and an olive grove. When you type "villa" into the search bar, you should get 2 results, but it shows 4 (duplicate results). "Olive grove," which is in the same category, only shows 1 result as it should. The ID displays of the listings are as the ones  on the screenshots taken  from phpmyadmin

The problem is solved. The issue stemmed from the word "Villa." "Villa" has the same meaning in both English and Turkish. I organize my listings in two languages, English and Turkish. Since the search is word-based, it uses each listing twice. I solved the problem by replacing "Villa" with "yazlık ev," which means "summer house."
