Unwanted template change along with language change

Hi,
my site: http://fotoobrazy.immago.pl
I've instaled template 12541 v 1.0 from osc.template-help.com/free_zen_cart_template/index.php

I'm experiencing unwanted template change to classic/default template when language is changed. I want to use only 12541 template in polish and english.

Configuration:
launguage - polish (default)
template - default (all) - Classic Contemporary Green

There is no possibility to delete Classic Contemporary Green template in admin.

I've looked throught forum, but didn't find any solution, so please sugest what is wrong in my instalation.
Case is present from instalation.
Instaling any addons didn't correct or messup.

I've instaled:
-ZenCart 1.3.8
- template 12541
- polish localization
- column_layout_grid_for_product_listing_1-3-8.zip
- ultimate_seo_urls_2-107.zip
- zen_lightbox_1-5.zip

I'll appreciate any help.

You'd probably need to contact Template Monster to see why that happens.

One way to know for sure is to change temporarily to the 'Classic' template and see if the problem continues.

OK, I made small trick :)
Changed tempate_dir in template_select table from classic to my template directory.
May be not professional, but works ;)

Thank you for your time.
