Hi amitmozar,
We checked your site and the categories are not turned off. The additional Custom CSS code have been added to hide the categories from being visible. We found our support team have provided you the Custom CSS Code to hide the categories few months ago.
And for the post that goes to ‘uncategorized’, please check the respective Post and check whether the categories are really unassigned. If unassigned then assign the categories again.
Thanks
