Lang issue in template manager

I have installed 2 same templates on my site, to have some pages display with some css atributes and some with others.
But the second template manager shows language with out render.. (see attach)
any recommendation on how to solve this is almost imposible to properly manage the template like that.

here is the attach, thanks

You are missing language file. Please download "gk_twn2_J!25.zip" and extract it. You will see language folder inside.

Copy "en-GB.tpl_gk_twn2.ini" into "language/en-GB/en-GB.tpl_gk_twn2.ini" in your website.

See you around...
