If I write new text then, and switch to source it shows the correct formatting tags. But its strange why it shows on the live site the source version and not bold / with paragraph for example.

If I make new product as per normal I don't experience any of this. Just two plugins (that never use to do this until perhaps over a year ago). I have seen a file called sanitise somewhere before, in admin fileset I think. I am fairly sure it is stock version.
Based on that and a brief review of a plugin called quick updates, the issue is oversanitization when submitting content through the admin where the sanitization code has been applied. The plugin appears to offer sanitization processing, but it appears to apply only strict sanitization which is applied even if no sanitization rule had been added... At any rate, the issue is not with ckeditor but instead the plugin(s) associated with what is being seen.
