But shouldn't the interpretation say '45% greater risk of outcome' instead? This way, it would be consistent with the interpretations below it. If someone could explain I would greatly appreciate it

No, it doesn't. Your attachment says precisely what you have below- that a "relative risk" of 1.45 is a 45% greater risk.

I looked at the attachment again and it clearly says '145% greater risk of outcome' (I'm referring to the first highlighted part). Where does it say 'relative risk" of 1.45 is a 45% greater risk'?
