Weird underlining after parentheses

When typing a close parenthesis and then an open parenthesis (such as when citing to a section of a statute), I get this weird underlining.

For example, when typing Section 301(a)(1)(G) there will be underlining between the “a” and the “1” and the “1” and the “G”

Not sure what this is and why it occurs.

Upon further review, it looks like the problem is that the close paren “)” always is underlined. I don’t have the underlining formatting activated and am not certain why this is occurring.
