Localization has resulted in impressions drop.

Hello.

I have just localised my app into two new languages. This is my first attempt at localising, and from what I read, I should expect at least the same or greater amount of downloads/impressions.

Everything regarding the app has been localised, such as screenshots, keywords, the main app etc.

It's been three days since, and the impressions for unique devices has dropped to about a 1/3 the daily average. I don't understand why this would happen. The app has been localised by a native speaker, so the keywords should be alright, and even so, the app should be ranked normally with the English keywords.

Has anyone else experienced something similar?
