Hi again,
All borders when hovering are set to the same color code with the primary color, the main color of the entire website.
To change this color, please go to Edit page with Elementor: https://prnt.sc/19p1dpu -> Icon Menu Bar -> Site Settings:https://prnt.sc/19p1n83 -> Global Color -> Setup color: https://prnt.sc/19p1xcy
If you need to help, please send Admin web account for me, I will check and try to help you.
