Well of course. I'm not saying it Isn't a bug, because it could very easily be one, however, it could just be one of those quirks of the game where SI have to have something coded as a possibility to happen irl that happens more often in the game than it realistically would in real life.
Things like that are always going to happen with FM because of the sheer volumes of people playing. Add in that you're only loading Columbia so it'll vastly limit the amount of International sides that'll have full first team squads and it's easy to see how it's a possibility if it isn't actually a bug.
