in the deals table we have five columns
name, description, private_note, coupon_conditions, coupon_highlights
and when you enter a deal from the admin panel, the above mentioned columns get filled, and they store information for english language. Now in the deals table we have five columns for the deal entered in the another language, which are:
name_por, description_por, private_note_por, coupon_conditions_por, coupon_highlights_por
now when you enter a deal in the other Language from the admin panel these columns remain empty. the only columns that get information from the admin panel are for english language.
that's why when you enter a deal from the admin panel, you see everything when you are in english language but when you switch to Portuguese language you get empty result in these columns.
