Change / delet underlining

Hello!

I am using the jp-adventure template for my homepage.

The headlines are underlined with a thick red line and then with a gray line.

I tried to remove the underline but I couldnt find out how to do it.

Could you please inform me how to remove or change the underlining of the headlines?

Attached I send you a screenshot for a better understanding of my problem.

Thank you in advance for your support.

Best Greetings

Mark
