F# Yaml type provider - f#

Question

I have tried using a Yaml collection of maps in my config file :
Companies:
- code: 11
name: A
country: FR
functionalCurrency: EUR
- code: 12
name: B
country: GB
functionalCurrency: GBP
However, when trying to read it with the type provider, it only finds the first result of the list.
With :
open FSharp.Configuration
type CompaniesConfig = YamlConfig<"Config.yaml">
let config = CompaniesConfig()
the output is :
val config : CompaniesConfig =
Companies:
- code: 11
name: A
country: FR
functionalCurrency: EUR
Trying to parse the code online worked, hence I wonder if that is a library limitation or... ?
Thanks for your help

You need to actually load the file, not only get the schema if you want to work with it directly: config.Load(yamlFile). This should probably more explicit in the documentation. I used the sample file in the link.
#if INTERACTIVE
#r #"..\packages\FSharp.Configuration.0.6.1\lib\net40\FSharp.Configuration.dll"
#endif
open FSharp.Configuration
open System.IO
/// https://github.com/fsprojects/FSharp.Configuration/blob/master/tests/FSharp.Configuration.Tests/Lists.yaml
[<Literal>]
let yamlFile = __SOURCE_DIRECTORY__ + "..\Lists.yaml"
File.Exists yamlFile
type TestConfig = YamlConfig<yamlFile>
let config = TestConfig()
config.Load(yamlFile)
config.items.Count
config.items
And I get both items:
>
val it : int = 2
>
val it : System.Collections.Generic.IList<TestConfig.items_Item_Type> =
seq
[FSharp.Configuration.TestConfig+items_Item_Type
{descrip = "Water Bucket (Filled)";
part_no = "A4786";
price = 147;
quantity = 4;};
FSharp.Configuration.TestConfig+items_Item_Type
{descrip = "High Heeled "Ruby" Slippers";
part_no = "E1628";
price = 10027;
quantity = 1;}]
