Export import missing categories

Hi i have installed Export/Import Tool (V2.31) on an opencart Version 2.1.0.2 installation.

All is working fine when i import my categories apart from ttey are not showing up in the Admin area. They are in the database and when i add categories manually they appear in admin and also when I export the cats they are all in the spreadsheet.
I've noticed in the db that the manually added ones appear in the category path table but not the imported ones.
I've checked my spreadsheet and duplicated the settings for the manually added cats but still they do not appear.
This also means that in products i can't add a category as they are not appearing for selection.
I've not tested importing my products as yet but am on with it.
Any ideas. (i've searched the forum and the tinternet all i can find is that it may be a language issue but both my admin and front end are set to English. When I export I'm not getting a language column in my spreadsheet, should there be one ?

Resolved , I was missing input in the layout column
