Very difficult to read rancher documentation left menu, bad color contrast

We got again the same issue as described here before, unfortunately closed, so I have to create this new post.

for example go to http://docs.rancher.com/ and than on the left menu click one of the item to expand it like “Using Rancher through Rancher-Compose” you will see the items with a color #99a3a8 that has very bad contrast, it fails all the accessibility tests, it is very hard to read.

Below test results from WebAIM: Contrast Checker

Could you please fix it again?
thanks
