Italicized text showing as Underlined?

in my sciFi book, I italicize the names of the various spaceships…

which looks perfect “in” the scriv files…but when compiled as a .mobi it is underlined instead?

PLUS I copied the book blurb from Word pasted it in using the same style and that whole paragraph is now underlined too in the .mobi …yet it is NOT in the scriv file???

Shoot…there is a preset X in the checkbox to do that…sigh…who 'n heck broke into my home office and clicked that???

Thanks… I should have searched here first…
