CTA title color

Hi, I have a problem with the CTA and the color of the titles.
In my test post (https://travelsurfrepeat.com/test-nahrady-za-wpbakery/ – the first two-column block), the title is white, which is what I want.
But when I inserted the CTA into my existing post (https://travelsurfrepeat.com/how-to-fly-from-natakhtari-tbilisi-to-mestia/#where-to-stay-in-tbilisi), the title is not white even though I’ve tried to select the white color again.
Any idea what’s wrong? The only difference is the title is H3 in the test post and H4 in the existing post.
