Used Avia Layout Editor on Blog Post – Single Post has no title/author/date

Dear support staff,
I know someone posted this question a couple of weeks ago, and I’ve read the answer.
When used Avia editor, the blog post has no author, no date, no category, nothing.

And this is the answer:
That is as expected, using the ALB for posts will make the post act more like a page. You can add most things manually from the builder if you like, or you can switch to the default editor and still use ALB elements using the Magic Wand tool (top row to the right with blue background): http://imgur.com/GReRtrs

My question is:
is it possible to add category, date etc. manually? How?
Or is one or the other? Avia editor/pages without date and category, or default editor, and posts with dates and category?

Thank you very much
