Sorry for the late reply. your post has been marked as spam for some reason, so I haven’t seen it so far.
The free version of the theme serves as a test platform for the Pro theme, so sometimes it happens that some new features get earlier on the free theme than on the Pro. In this way, we can identify and eliminate any possible shortcomings of the new option.
For this reason, the header divider does not yet exist in the pro version, but we are preparing it for the upcoming update, hopefully, it will happen in a short time.
