All GraphQL SDL schema fields shown as depreciated in GraphQL-Voyager regardless if they actually are

I’m trying to check my GraphQL Schema created in SDL using "GraphQL-Voyager", but it always shows all fields are "DEPRECATED" even when none of them are declared as deprecated. For an example, the following simple schema would encounter the issue:

schema {
  query: Query
}

type Query {
  get_CONTACTS( id: ID! ): CONTACTS
}

type CONTACTS {
  CONTACT_ID: ID!
  FIRST_NAME: String
  LAST_NAME: String
}

Screen shots showing the issue

I’m new to GraphQL and currently just following what I’ve learned from an online course I purchased earlier, not sure what else I can try.

Any information will be greatly appreciated!

Thanks!
