Undesired Font Color/Underline change after hyperlink

Apologies if this is answered elsewhere. After putting a hyperlink in a text document, my next line will default to blue/underline text when I want it to stay at the default black no underline style for the document. To change it back I have to go up and right-click the blue font color on the toolbar and I use CMD/U to remove the underline. I’d prefer not to need to do this every time I use a link. I’ve looked through the manual, preferences, this forum/google and haven’t found a way to change this behavior. I’m guessing it’s something really obvious & simple but I’m stumped.
