Text font size not going beyond 1

Hey, i use Unity version 5.6.7(because my system in 32 bit). I am learning unity and am following a guy named Brackeys on youtube. So i was trying to increase my text size and it is not going beyond 1.
Here’s how it looks like

Do you know how i can fix this? Thanks.

Update: I tried increasing the size to a much larger size like say 60 and it increased. Probably 1 is some preset size.
