Hummingbird Low Score

Have Two issue:

Issue One:
Hummingbird showing low score for optimize images in Performance report, and in Google Page Speed. However, the images shown are optimized.

In GTmetrix, the optimize image result shown are different when compared to results of Google Page Speed. That's different images are listed under Google Page Speed, and Gtmetrix for Optimize images result.

Issue Two:
Hummingbird CDN is enabled, but GTMetrix shows it as disabled.

Please advise, support access enabled.
