Thanks Jonathan Bardo, fixed both of the issues. It is working fine now. There is one more issue (not exactly one) which I am unable to fix. The search field is missing on the site, may be because of poor handling of setting from my side. If you could help in that too I would be delighted. Thanks again.
For me its now 5 (*****) star theme, simple and elegant. Will keep giving feedback/suggestion as I encounter problem/requirement.
Thanks to the developers @jonathanbardo and Github team who worked on it. Its my first website and will always remain thankful to the developers.
