Steemit bug - Unable to save private post display preferences

Hello Steemians,

Today I posted a post in NSFW category. The post was hidden because of private post display settings.

So I clicked on display preferences and navigated me to the settings page.
while updating private post display settings I found a bug that on the selection of a preference given in the list it is not updating my preferences.

On refreshing the web page or navigating to another page, it is not updating my preferences
Please look into the bug.
