You need to select the pokémon you want to look for. They're
ordered by Dex entry, so it might require some scrolling before you
find the starter you're interested in.
There's also a chance that the starter you selected, doesn't have
any eggs in the Tall Grass [as indicated by the 0 behind it], so if
that's the case, you need to wait for Eggs to be released before
you can hunt for them.
If it's neither of these two possibilities, could you give some
more details [what do you do? What have you tried?] and maybe a
screenshot of your Tall Grass page?
Kitties! Riako has no idea what he unleashed with that update🙀
