Pictures of Sims at bottom suddenly small

I was playing Sims 4 (no cc, no mods, base game + a couple stuff packs), my household had a baby, bringing the household to 7 total sims and as soon as the baby's picture showed up, all 7 sims's pictures became tiny. No other part of the UI has changed (or at least not as much). I did adjust the UI in settings and that changed everything, which doesn't solve the issue.
