Trouble With Another Agency's InDesign Templates
Took over a client from another agency and am working on some of the templates the other agency created. I'm mostly self-taught in InDesign, so am discovering lots of cool new tools thanks to this other agency's templates, and also encountering some road blocks.
This image is not linked. How has it been inserted? What are the dotted lines around the image?

How is this underscore/line created? It's not underlined text, it's not _____, it's not a drawn line. It appears to be in the text box. However, I am unable to select it and when I try to delete that unnecessary space between the bounding box and the first line of text, the line disappears.

The box behind the header is connected with the textbox. How is this done? It's not grouped with the text; it seems to be a part of the text. I can't figure out how to access it (change the color, delete it, etc.).

Any insight on the above would be amazing! Thank you in advance.
