does anyone know why this happens? im trying to change the color of a link on a nav bar for example and its show this error

hello, can someone please tell me, what is the general guidance when you try to edit text that is off the screen? for example, the banner marquee tool has half of the class not visible in webflow so you cant edit the text to what you want it to say. my thought is you could just duplicate the class of what you want to have written or copy paste the text over again and just delete the other ones. is there a better way to do it ? i noticed some of the components have similar stuff to this.

Sorry if this is too general of a question, I'm decent at figma but trying to get familiar with how to best use the relume kit, but when you copy components there is both a mobile and desktop. is the best standard practice to ungroup these and then build out the desktop and mobile next to each other ? i was trying to find a best use guide video or some general video for the figma relume kit. why would they be grouped together like this ?
