>that's the plot hole
there is no plot hole, none of them have husbands or human males they're married to. they're the remaining survivors of Reflestia's terrible rule. they haven't been married nor mated yet.

For clarity's sake, Harpies require the permission of the active Queen in order to both marry and be allowed to mate and have children. Reflestia was actively declaring war on multiple other races, one of which was humans, and it's explicitly said this severely impacted the relationship between humans and Harpies to the point none of them wanted to be with one even when they kept trying to ask. And Reflestia didn't care because she basically just kidnapped selectively chosen human men after burning human settlements to the ground to have them gang-raped and/or just build up a harem for herself. She both wouldn't permit them to have relationships and was actively sabotaging them with her actions. It's also revealed not only was Reflestia forcibly conscripting the Harpies to fight in her army, she was also willing to conscript the children and force them to fight in her army as well. The Harpies were also trying to keep the humans out of their village until they were certain Reflestia wasn't going to succeed out of fear for their safety.

tl;dr, putting aside how she ruined their reputation and/or sabotaged their relationships:
If you're wondering why there aren't any men in their village who were there before it all started, it's because Reflestia 100% either enslaved all the Human Men that were living in the village at the time of her rule against her people's wishes or forced them all to fight on the frontlines of her army with the rest of her soldiers. She reacts to all dissent with the same solution (violence). Any Man who resisted her authority is dead. Anyone conscripted into her army is dead.
They're dead.
All the Human Men who were living there are dead, along with their Harpy Lovers/families.
