Results are identical for all parsers

[Graylington]

Am I missing something?

I tried using your example graph and I still get the same results. I see slight differences, but nearly identical.

I have to update the examples since I took that when stable-diffusion-webui was version 1.4. Many changes have been made on both UIs since then, so it'd probably be difficult to get identical results again, but any difference means it's working :)
There won't be many differences if you don't have varying weights like a (word:1.2) ((here) and there)

A quick and easy way to test different parsers is to use OneButtonPrompt.
