How to arrange blocks in 1 row in wordpress theme?

Question

css

Greetings! There is a test site with the Parallax one theme installed . In the Our Services
section , I added a 4th service that is not intended by the theme to be located in one row, although there are styles for parallax_one_grid_col_4 . The topic itself is so confusing from any changes that I can’t even understand how and where the block output is formed - so I can’t figure out how to arrange 4 blocks in 1 row - any ideas? I would do it with the help of styles, but there is a joke: 4 service block with this constantly jumps from column to column..
