I noticed reputation changes on the recent page but it does not change next to the name on the top bar. Is this planned or a bug?
It's unclear what you are referring to here.
If you mean your reputation on meta, that is synced hourly between parent and child meta. Votes here on meta do NOT affect reputation in any way.
If you mean your reputation on the parent site, I'm not aware of any bugs that would prevent reputation from working as normal.
