weird effect when applying preset format

This is just strange, but it’s annoying and I’m wondering how to get rid of it.
For the first time I saved some formatting as a preset.
When I applied it to a section, suddenly the background of the section was blue, and the whole thing had an outline around it.
Which I can’t get rid of.
I’m attaching a screenshot, but I haven’t had any luck so far on this forum with screenshots appearing. So I hope my verbal description is enough to get me some help?

The blue indicates a Preserve Formatting block. It won’t be affected by anything you might do with the Compile command.

To get rid of it, go to the Format -> Formatting menu and uncheck the Preserve Formatting option. See Section 15.4.6 in the Scrivener manual for more information.
