H2 Headline Text only first word is H2 size

I have uploaded the demo pages and am using them as a guide for my site.
When I changed the text of the homepage slider second image, the headline text only has the first word in H2 size. the rest of the words are smaller and should not be.
I only edited the text and this is what happened. Cannot fix it.
In the visual composer it is set as H2 title with purple text color.

Here is my site:

look at the second image in the homepage slider.

please tell me how to fix this.
thanks.
