Question About Duplicate Content?

Yesteday, I used the crossposting tool Masdacs to post an article to SteemIt, Golos, Whaleshares and Medium.

The post was sent to SteemIt almost immediately, but the site is now stuck at 'Posting on Golos' for more than 12 hours.
If it doesn't get past this, my article won't be posted on Whaleshares, nor on Medium.

Now here's my question:

If I cancel the process and post the article on those two sites manually later today, willl get in any trouble because I'm posting 'duplicate content'?

I hope someone can help me out with some good advice...
