Slide #1 text shows larger than others on iPhones only

All Content Slider Modules on the website have an error on iPhones only where the text of the very first slide is significantly bigger than the others. I could not identify CSS causing this. I used Xcode to try and debug this issue but still can’t determine the cause or find a solution.

Here are example pages:
