Help to center a row

I’m working for the full width in the block

on the 1280 screen it looks perfectly aligned, including tablet or phone

with the customized class should look like this

but the reality is that it only aligns it to the left

the lower block of three columns, is centered, this error or inconvenience is rare, the configuration is perfectly for each column for the two blocks!

I do not understand how it is that if one block is centered and another is not! It’s very weird…
