Legendary marks cap glitch? (possibly bugged nightfall reward)

I noticed that my marks were resting at 105. I finished the nightfall and still had 105 at the end. I'm wondering if the nightfall was supposed to give me the 25 or its that we cant gain anymore marks past 100 unless we dismantle legendaries.
Would like some input from others if ya'll got the same outcomes.
I would just like to to make the point to becareful of your marks if you're past 100 legendary marks
