If you do not use osclass 3.7.1, then you have old recaptcha. I recommend to use nocaptcha recaptcha plugin that is free and can be found i.e. on osclass market, using latest version of recaptcha.
Regarding fields in 3rd step, those are comming from SEO plugin.
Icons can be added from theme settings or manually to oc-content/themes/veronika/img/large_cat
