Virtue-Sidebar

I like virtue(free) with very good customize-features.
My problem is sidebar visibility.
My Page/post setting is “no side bar” as default.
But I still can see the sidebar at single post view.
I checked at post editor(classic) and found post option shows
Display sidebar?->yes
I do not understand why this is showing “Yes” though my default setting at theme option is “No”.
I do not want to change it to “No” for each post manually. Otherwise, it has no meaning of “default setting”.
This is very important to the users who want to display sidebar only on home landing page.
Will you please check and advise your helpful comment?
TKS!
