Jumping columns when hitting enter at end of paragraph
Just like my subject line says, when I hit enter at the end of a paragraph/line, rather than taking me to the next typical paragraph line, it's jumping me to the next column. I have spent the better part of the day trying to find a solution to no avail.
I am up to date, but I did get a new computer (transitioned from HP to Gateway, if that makes any kind of difference).
I've attached a screenshot. So, the arrow is where I first experienced the issue (the other paragraphs ahead of the ones in question were already in the document, as they had been pulled over from a previous document - I'm operating on a template of our calendar). In every place in the document, if I hit enter after something, it automatically jumps to the next column at this point.
