Help me understand Family Leave for work-at-home careers

Hello! I'm having trouble using Family Leave for the work-at-home careers and am trying to figure out if there's a bug going on or if I just don't understand the gameplay.

Let's say a sim works at 10am in a career that offers working from home. They are about to have a baby and I got the notification that they are eligible for family leave.

I can wake them up in the morning and have them "take family leave" on the phone. It confirms that they are on family leave for one day.

Then at 9am I get the usual popup with the options to go in to work, work from home, or take PTO. No family leave option on the popup.

If I close the popup, it behaves as if I selected "go to work". The career panel no longer says on family leave, it says Work in 59 minutes.

The "take family leave" option on the phone is now gone.

The sim tries to leave for work at 10am as usual. If I keep them home, they get the "missing work" alarm and call from boss, as if they are not on family leave at all.

If I choose PTO on the 9am popup instead, it deducts one vacation day, and the career panel says the sim is on vacation not on family leave.

Am I missing something?

Is there a bug? (I couldn't find an existing bug report)

Are work-from-home careers not supposed to get family leave because you can work from home as an alternative? (if so why display the notifications about being eligible for family leave)

It's happened with two households in two different save games recently for me.

I think those are the only two households with new babies and work-from-home careers I've played in quite a long time.
