It’s not a bug unless we can reproduce it. Please provide detailed information including screenshots, video recordings, public share link of your project, and published URL.
I think it has something to do with the interaction or flex setting on the parent element cta service-block. I can’t test this theory as I can’t publish your site. Try and remove either and publish, then do the same for the other if it doesn’t help.
Also, global class service-block is used three times on different elements here. This is bad practice.
