The answer lies within the message itself; '...due to RECENT events...'
I haven't the game files on me right now, but from screening the game code over the last few days I remember that the 'captured' flag is initially set to 5(?) and the 'end press' event (a.k.a. end day) has an option to decrease the counter by 1. I can't remember if it's a randomized function or happens every day, but basically it takes time to get rid of this 'flag' - might be that some other values or interactions can influence this process, but in the end it's a matter of time.
WAIT
this is Rebelious state, by using mindread on person you can see how strong it is (how long it might take)
you have many ways to remove it 1st and easiest is wait and keep that person in jail, you can use branding and jailer to made it like 3x faster
by using spells as domination and fear you can reduce it and slave will be good after 1 day (longer if you suk in magic)
you can also use POWER OF ALCHEMY and spike her with amnesia potion (instant effect)
or GOOD OLD rape to mindbreak and wait 1 day
