Problem with text transform of heading 3

The site in question is https://www.emini-turtle.com

I changed the text transform of heading 3’s from uppercase to normal. (Ideally, I don’t want any headings to be uppercase.)

So I included this in my child theme:

.entry-content h3 {
	font-size: 26px;
	letter-spacing: normal;
	text-transform: none;
}

But for some reason, some headings continue to appear in uppercase letters while some do not. There seems to be a weird trend where the first three headings or so are normal but then the two headings after are uppercase, and then it’s back to normal headings.

You can see this on my blog’s Subscription page, it’s “NOW, ARE YOU READY TO BE ON BOARD?” and “SIMPLY MONTHLY” followed by a normal “Differences in Accuracy and Frequency.”

And on the Faq page, it’s “ABOUT HOLIDAYS” and “ABOUT UNETHICAL CONDUCT OF USING OUR STRATEGIES.”

I must be overlooking a simple reason that it’s doing but I can’t figure it out. Thanks in advance for the help!
