W3C Errors with Meta Slider Using The Flex Slider

Here are my details:

WP Version 4.8
Divi
Mac OS 10.12.6
Home Page: https://izteremka.com/

Problem:
I have installed the latest version of Meta Slider.

When activated I get two (2) W3C errors.
They are as follows:
1. Error: No p element in scope but a p end tag seen.
From line 2499, column 2109; to line 2499, column 2112
div></div></p>?<p>Th
2. Error: Element style not allowed as child of element body in this context. (Suppressing further errors from this subtree.)
From line 2528, column 108; to line 2528, column 126
;</script><style media=”all”>.flex-
Contexts in which element style may be used:
Where metadata content is expected.
In a noscript element that is a child of a head element.
In the body, where flow content is expected.
Content model for element body:
Flow content.

When I deactivate Meta Slider the W3C errors go away.

I tried to edit the Meta Slider file, but I could not locate the string.

I need help to correct this problem.

Thanks in advance.
