The error with the megamenu was not fixed even after the last update.

I get the same error

Error: Element style not allowed as child of element div in this context. (Suppressing further errors from this subtree.)

When I check the code of the page I get this <style data-type="vc_shortcodes-custom-css"></style>

Is there a way to fix this?
Should I do some extra steps after updating to version 6.2.3?
