Danilen V. ah okay got it, yeah this can sometimes be tricky. Especially if your navbar is a component. One trick you could try is to duplicate your navbar component, and unlink instance. Then assign a nav link to the homepage, deselect this nav link, then try selecting it again - you should see the green "current" combo assigned to it, and you're in the right state to then modify styles for the current nav item.
If a loom would be helpful here, let me know, happy to record one for you.
