I didn't see anything during that timeframe, but maybe she overdid the whitewash over Jason's death? You can see from what is left that she was running with the first of two separate narratives - the first narrative was that he wanted her to raise the children in the US if something happened to him; second,their marriage was in trouble because he was abusive. The two stories don't fit neatly together because there's no factual evidence for either scenario.
In the earliest posts available, and in the first viral FB post I ever saw (Jan 2016) there does seem to be the implication that he just died suddenly and his cruel relatives had snatched away the children, even though he would have wanted her to raise them herself in the US. This was when she was focusing the social media campaign on getting the children back, not on defending herself for a murder charge. Even the earliest ones remaining are worded oddly when you consider she was being investigated for his murder. The ones she deleted might have seemed more strange in that context.
Is it possible that she had thought the police had just dropped the question of how Jason died, so she was 100% focused on getting the kids back? Then when she realized the murder charge was looming, she quickly got rid of anything that was too family-focused. Later, she had to drop the custody question (unwillingly) to concentrate on the murder charge, but even Molly would have seen it was a bit of a stretch to combine the two narratives and claim that Jason's dying thought as she beat him to death was that she was the woman he wanted raising his children.
