Hardener/Scan issues from Defender

Having a few problems with Defender:

1) Hardener always says I'm not running the current version on WordPress?

Also get 2 other issues: Prevent Information Disclosure and Prevent PHP execution, but there is no clear information. Both say "Your website currently run on , which has not yet supported. Please contact our support for more information"

2) When Scan finishes there are 2 errors in code somewhere that show up at the top of the screen, but I can't see them entirely. I don't know where or what they are related to.

Screenshots attached for all issues.
