how to remove buttons on slider on home page

Hi, I’m in need of help, on my home page on the three slides are two buttons (i think these are buttons, I may be wrong) someone else wrote the original enfold content and I am now learning how to change things, they are small boxes and say ‘talk to us’,’ learn more’ and ‘about’.

I want to remove these but I just can’t figure out how, they don’t show up in the caption section of the slider.

please can anyone help?

thank you

Stuart
