Rubymine will not step inside any code blocks in RSpec

I have just installed Rubymine on my MAC laptop running OSX 10.11.3

I'm trying to use it to teach myself RSpec but am having a weird problem; when I run the code inside Rubymine, it doesn't step inside any code blocks, either in debug or run mode.

NOTE: I've just discovered what the problem is but will post this in case anyone lese hits the same issue. I was following an online tutorial that recommended the #method_name syntax shown below. This # caused the problem I detail below. Removing it allowed me to debug and run normally. Perhaps this is a bug in Rubymine?  

The problem -

I have this simple file:

require 'rspec'

describe '#enforcement_search' do

  before(:all) do
    puts "HERE"
    cfg = ENV["API_CFG"]
    puts "ENV - #{cfg}"
  end

  context 'with correct parameters' do
    it 'returns a record' do
      puts "HERE"
    end
  end
end

When I run it from the command line I see the puts statements as expected. Within Rubymine I see nothing in the console. 

If I step through it in the debugger, I hit the line

before(:all) do

but then skip on to:

context 'with correct parameters' do
  it 'returns a record' do

Both of which are hit if I put a break on them, but then it skips over the puts statement in the block.

So it seems that putting the # in the describe causes RM to skip all content in code blocks...
