not completely sure what's going on.
it looks like the code I gave you doesn't target the first part .h2 services branding link.
When you undo the old hover color changes you made in the webflow designer you'll see what I mean.
The reason could be that you deactivated the link in there, and so the browser might not recognize it as the 'a' (which denotes a link) anymore. (not sure though)
So either reactivate that link or or delete the 'a' in your first line of code in the picture above and see if that helps.
It could also be a simple misspelling thing somewhere in there. Make sure that all the classes in your style code are exactly as the ones on your webpage. It's pretty easy to overlook something.
Other than these things I'm out of ideas for now
