Elementor Menu – Dropdown Menu showing a square?

Hello,

Thanks to anyone in advance for taking the time to help me out!

Does anyone know why the drop down arrow on the menu is not an arrow but a square? It shows a square next to “Semillas” as well as info.

The inspect code shows:

<span class="sub-arrow"><i class="fas fa-caret-down"></i></span>

How could I fix this?
