I think it’s just a fix to put the game back to how it was a year ago before it broke.
At some point with a patch update, the game started ignoring the hidden gender preference on flirt options that appeared as auto suggestions. Sims also started autonomously flirting more with sims that weren’t their gender preference, which was really noticeable at the Romance Festival.
Previously, if you clicked on another sim that wasn’t your sim’s gender preference, it wouldn’t suggest flirting with them as a top menu option. That doesn’t stop you manually choosing it from the romance menu - it just doesn’t push it on you in its suggestions.
