Translate more efficiently

Today I try to translate the mod of Fallout Shelter from English to Chinese. I click a button and it jumps to Crowdin. I have tranlated all of the title on it, but when I back to Wemod, it still show English, I can’t see my transalation. What is the matter?

Once they have been translated they must receive enough upvotes before they are published in the app. This is to prevent users from going through with google translate or another translation service and just translating everything.
