F# WSDL Type Provider and Confluence

Question

When I use the WSDL Type provider to create a client for Confluence SOAP service then I get all methods with (unit -> unit) signature.

#r "System.ServiceModel.dll"
#r "FSharp.Data.TypeProviders.dll"
open System.ServiceModel
open Microsoft.FSharp.Data.TypeProviders

[<Literal>]
let ConfluenceServiceWsdl = "https://developer.atlassian.com/rpc/soap-axis/confluenceservice-v2?WSDL"
type ConfluenceService = Microsoft.FSharp.Data.TypeProviders.WsdlService<ConfluenceServiceWsdl>

let service = ConfluenceService.``Getconfluenceservice-v2``()

service.getPages;;
...
val it : (unit -> unit) = <fun:it@3-1>

but it should be something like Vector<PageSummary> getPages(String token, String spaceKey) - (from Remote Confluence Methods documentation)

What am I doing wrong? How to create full-functional service client? Is something wrong with WSDL?

P.S. Confluence SOAP WSDL was generated by Apache Axis.
