Categories And Webservice

[El_Matella]

Hi,

 

I am trying to create new categories on my prestashop with the webservices but I am having some difficulties. 

 

I can create categories, it work in some way, but I don't understand why my categories just don't show off anymore in the admin panel. 

 

So I think that the database must be corrupt somewhere but I really don't know where. Here is my database content:

And here is a screenshot from my Prestashop Admin:

 

 

So a looot of categories are missing and I don't know where to look to fix that...

 

Any help is appreciated

 

Have a nice day
