fanSpeed UI Display change

I added patch content as you said, % disappeared. Thanks!! But the problem is, % still comes out in the History tab, what should I do to make it not come out in the History tab?

And when I checked, even though the rest of the parts (such as the label on fanSpeed) were modified, all of them are marked as original in the History tab. Is there a way to make the modified content come out in the History tab as well?

And can you take a look at this one, too?
