I've noticed around here that we have people who actually know what they are talking about and people who think or pretend they do.
Everyone gets so caught up in the hubbub of who's right, and who's wrong. But we all forget that every situation is different and within every situation are endless variables which we don't and can't control and nor can we always know about them.
In the case of incubation temperature and humidity, they can very immensely because of environment alone. We don't all live in the same house. We don't all have the same climate. We also don't all use the exact same products. Some products have to be calibrated or used differently or are meant to be used in different area (outside instead of an incubator). So if we are going to offer our advice here, we should probably all stop to consider everything.
Like where is the OP? What product are they using? What is the intended use of said product? How does said product measure temp or humidity?
Just my two cents.
You have wisdom beyond most of the self proclaimed forum experts.
