Logo's PR department still hasn't responded to my request about the subject, but it looks like The Wrap got the full story:
The network was blindsided by the disclosure, TheWrap has learned, and is scrambling to contain the PR nightmare as gay activists join the growing chorus of critics for a show that’s been dubbed the gay version of “The Bachelor” and is set to premiere Sept. 8. A person close to the situation told TheWrap the network followed “standard protocol” when vetting Sepulveda and that “nothing came up during the background check.” “The network didn’t find out until well into production,” he added.A reader of mine put it best when he said the producers of "Finding Prince Charming" must have used the same firm that vetted the Trump leadership team.
