On our homepage (https://www.footlevelers.com), the hero banner is using an H1 tag for the text "Custom Made to Your Feet" for both the desktop and mobile version. These tags are in a RAW HTML add-on. SP Page Builder is changing the H1 tag on mobile to an H2 tag even though the desktop version is hidden on mobile.
Why is it changing our HTML within the Raw HTML add-on? It shouldn't be messing with the HTML in the first place... and especially since the H1 tag within the desktop version of the hero section is hidden from mobile browsers.
