Text Title not showing when slide effect is down

Hi,

The title text on certain pages are not showing when the “slide effect” is down. I would like these to show so i dont have to have text against my background image in each box slider.

On my home page – https://www.cockatours.com/ – All text titles are showing on all box sliders.
But if you have a look at my other page – https://www.cockatours.com/othertripsoffers/day-trips/ – The text title does not show therefore i have to put text on the background image so people know which location it is.

Is there a way i can make it show? I have already tried making text smaller & spacing will not work either.

Thanks!
