Strength training on Enduro

Hi. Two days ago, I was doing strength training and I was able to edit reps, but I couldn’t add more than 44,9 kgs (99 lbs) of weight. Why couldn’t I add more? Am I missing any options? For example, if I am doing leg press, I want to be able to add 150 kgs but currently i can add 44,9 kgs at most. I don’t want to change numbers in Connect app after I finish my workout. I want to do it on my Enduro as I was able to do it on my Vivoactive 3.
