w3 Validator error

Hello after installed free version of metaslider , I try to pass the w3 validator and I get the below error :
/——————————————————————/
Error: Element style is missing required attribute scoped.
From line 93, column 5; to line 93, column 50
der”>↩ <style type=”text/css” id=”metaslider-css-22″>↩
Attributes for element style:
Global attributes
media
type
scoped
Also, the title attribute has special semantics on this element.

Is any way to fix it ?
