If in the editor, you have a specific value set for the HTML tag for this element (SEO) setting on a text element and, in run mode, the Bubble inspector shows the expected value (say, H1 for example), however, when inspecting that text element with the browser console, it shows a different HTML tag (say, H2 for example), it could be that there's a style attached to the element.
The HTML tag for this element (SEO) setting can also be set within a Style. If a text element has a style attached to it, it will follow the HTML tag setting of the style rather than what's listed in its direct property editor.
Detaching the style from the text element or updating the HTML setting within the style should resolve the inconsistency you're noticing when inspecting the element in run mode.
