Google add sheets problem (SOLVED)

Hi, in my google sheet, i added several sheets to my main one but I cant access to the terms in those sheets. The localize component keeps showing the error of either 'not localized' or 'different language source'.

How do i access to them? Btw i am using Playmaker

thanks

UPDATED: turns out that the correct keyword is 'category'. So upon searching for i2 localization category, i found the answer.
