Another writer reminded me that by entering the contest, I couldn't move First Contact #1: The Strigoi, behind the paywall. I'd either forgotten or, more likely, misread the rule.
I want to thank awnlee jawking for pointing that out. He also suggested I could upload the corrected and expanded version behind the paywall and upload that version for sale.
I think, rather than doing that, I'll leave the version here as is and upload the other version to Bookapy. I'm not ashamed of the original one that was published.
However, I'm angry at myself for rushing through and not letting my editor have time to work on the story in advance. I plan to put the new version (which is about 1000 words longer) on Bookapy today, though it may be late in the day.
Check it out here, First Contact #1; The Strigoi.
