Data Warehouse new UI Scroll

Existing Option: 

When am trying to scroll down for adding the location when my browser option is 100%, am not able to see scroll bar options below. (Refer the image attached below.) Every time, I have to reduce my web browser size to 80% and then select the options further.

Additional Option:
So, I would like to add the point as to optimize the page in a way that even when I see it in 150% zoomed option it has to get modified according to that.
