How to align padding in owl carousel 2.3.4?

Question

css

Installed Owl Carousel ,
which has a property marginthat sets the indent to one side.
But the padding doesn't match the grid padding from bootstrap4?
I look at the eye, everything seems to be smooth, but between the blocks it is crooked.
How to set up correctly? Thanks in advance to everyone who fumbles.
