Problem Prestashop 1.6.1.4 at Google webmaster tools -> HTML Improvements

[ekylingga]

I use Prestashop 1.6.1.4 to online shop.
There are problems at google webmaster tools -> HTML Improvements -> Duplicate meta descriptions, Short meta descriptions, and Duplicate title tags

 

For example, link the correct url is:
http://jualserver.co...-poweredge-r730

not;
http://jualserver.co...redge-r730.html or
http://jualserver.co...redge-r730.html

This problem is because I make improvements to the website to delete all the data, and create a new website.
causing problems at google webmaster tools.

 

I attached a view of the problems at google webmaster tools -> HTML Improvements.

 

I hope from the experts prestashop, to provide input and the best advice.

This problem is very urgent and immediately resolved

Thank you

Regards,
