Header Size Issue

First of all, connecting to the site I’m having trouble with from a country other than Turkey and Germany is blocked because there are too many attacks. So if you can’t access the site, you can try with VPN.

I had customized with additional css codes in my Generatepress theme, but when I added links to my H2 headers, the size of my headers decreased. I want my title not to change size when I add a link.

Problem: https://ibb.co/p3L69B3

Normal size: https://ibb.co/ryrrLXQ

Additional css codes I added to my site:

.mg-nav-widget-area-back

background-image: none !important;
