[Tex/LaTex] apa6 documentclass makes ugly title-page

apa6titles

I have a problem using apa6 class and doc type: since paper has many authors/affiliations etc., title-page is set quite low, leaving only 'Abstract' title and the body of abstract on the next page. This looks quite ugly, and I dunno how to solve it. Please, help!

After a lot of search and trial & errors, I figured out this (semi) solution: simply generate abstract and keywords manually, i.e., do not provide this `fields' in preamble. However, I added small preamble-snippet for changing margins to make abstract prettier. This will cause warning messages, but the output will look nicer. Here is the corrected code from the above:
