This was introduced here OmniSharp/omnisharp-roslyn#1877 and boils down to this entry being incorrect.
https://github.com/OmniSharp/omnisharp-roslyn/blob/d5f7a77d298139185001c3105077e1da30819903/src/OmniSharp.Roslyn.CSharp/Services/Completion/CompletionService.cs#L62

Hopefully will be an easy fix. Going to check the rest of the tokens as well.
