It looks like you have the 'n' flag in 'formatoptions' set. Try
executing this,

:set fo-=n

and reformatting that paragraph. If that's it, you can find the
last place where 'formatoptions' was set with

:verbose set fo?

Hopefully, that will be the place where 'n' was added and you can
fix it. Also see

:help 'fo'
:help fo-table

I usually have 'n' included in my 'formatoptions', so I run into
this problem occasionally. When I do, I shift the second line left
(<<), then reformat the rest of the paragraph (gq}).

HTH,
Gary
