[LS] NPC Couples interactions overwhelming all other interactions/activities

At first the couples interactions (e.g. Watch Sky) from Lovestruck were cute, but I've begun to notice that they overwhelm everything else. Sims used to chat with each other, play basketball, use the hot springs, fabricate, etc. etc. - but now they just engage in couples interactions. If there are outdoor benches they're filled with couples watching the sky. At the Library they're kissing behind the books. It's not cute anymore, it's disruptive and annoying. Sims who aren't paired up just stand around doing nothing. It needs to be tuned down. 

One lone teen in the hot spring.

Nobody reading or using the pc's at the Library

No body playing chess and chatting at the park.

Is this a bug? Maybe not, but it makes things very dull. Especially on lots where I expect lots of activity. For example: The Makers Space from Eco Living.
