Fsharp WorldBankData keep throwing FS0039 error

Question

I am playing with FsLab and ran into issues when I was playing example from here:

https://fslab.org/getting-started/

open FSharp.Data

let wb = WorldBankData.GetDataContext()
let cz = wb.Countries.``Czech Republic``.Indicators
let eu = wb.Countries.``European Union``.Indicators

The error is Error FS0039 The type 'Countries' does not define the field, constructor or member 'Czech Republic'.

Any clue would be appreciated.

In case it helps, here is the package dependencies
