Webflow breakpoint properties change when starting from 1440px breakpoint

I created this design in webflow, however i started using the 1440px breakpoint instead of normal breakpoint and when i scale down, all my class properties are changing, the flexbox are suddenly static, typography colors are different, the list goes on.

This doesn’t happened to me when I was starting with the regular default ‘desktop’ breakpoint.

It’s frustrating because I will have to really dig into everything to recreate the same properties I have already developed in the larger breakpoint. Now i have to go back and forth and copy and paste all values to the children.

Could you take a quick look and tell me what i’m missing or doing wrong?
