Why does Genesis 10:5 say "they had their own language", when 11:1 says they all shared one language?

Genesis 10:2 The sons of Japheth: Gomer, Magog, Madai, Javan, Tubal, Meshech, and Tiras. 3 The sons of Gomer: Ashkenaz, Riphath, and Togarmah. 4 The sons of Javan: Elishah, Tarshish, Kittim, and Dodanim. 5 From these the coastland peoples spread in their lands, each with his own language, by their clans, in their nations.

Genesis 11:1

ESV - ¹ Now the whole earth had one language and the same words.
