If I had to guess, you may have picked up an item that was giving you a +2 (such as the circlet which gives you a +2 to animal handling).
The way Larian does it right now, they deduct all modifiers and then say what you need to roll on the die - things like guidance are currently throwing that off, since it rolls it once to show you, then rolls again to actually do it, making the display inaccurate, however if that wasn't the case, then it's worth looking into.
If you've still got the save file for that (ideally both - the earlier save and the later one), get to the dialogue that presents you the roll and mouse hover the check - it'll show you a detail screen about what modifiers you're working with; if you've got 'key of the ancients' or anything like that showing up in the latter one ,that may be the reason.
If the original DC, at the top of the hovering tooltip is actually changing, and you're not taking any different dialogue options etc., then that's worth submitting as a bug report, save files included.
