Umbraco version 13.1.1 Block Grid Data Type not accepting custom styles with. Override default stylesheet for backoffice layout

I all I am experimenting with Umbraco 13.1.1

In the block grid editor I have changed the bit

Override default stylesheet for backoffice layout.

Selected a style sheet to use and no matter what I try it won’t use my custom styles, when I inspect the element its looking else where and if I change the actual file umbraco-blockgridlayout in the assets on the sever itself those changes do not reflect either.

Anyone have any idea what I could be doing wrong.
