Can my own article resubmitted again after proper formatting be treated as 'copied' content from my earlier version?

I submitted an article on Corruption which was rejected only because it wasn't properly formatted during my subsequent editing. So I resubmitted the same article with minor changes - mainly highlighting some parts as 'bold' and 'italicised'. The resubmitted article was till today morning shown  as 'approved'. But suddenly I find it is shown 'rejected' as 'copied' content! Naturally, if I resubmit an article due to my not finding any other way to reformat the one submitted earlier, can my own article become 'copied' content of the earlier verion?
