Wrong length of Apple dataset

Screen Link: https://app.dataquest.io/m/428/guided-project%3A-profitable-app-profiles-for-the-app-store-and-google-play-markets/7/removing-non-english-apps-part-two

What I expected to happen:

Lenght of android english: 9614
Length of apple_english: 6183

What actually happened:

This is correct >> Lenght of android english: 9614
But this isn’t >> Length of apple_english: 7197

Any idea what step I missed with apple?

Thanks for noticing that error.
I should have spent a bit more time debugging it.
