I am using version 18.104.22.168. I also have this problem as well as "lifis". I don't see the SCORE field in the settings. I hypothesize that this may be due to the fact that reCAPTACHA v3 does not yet have enough traffic to determine SCORE. I did not find the module at https://thekrotek.com/opencart-extensions/free-extensions and I obtained it at https://www.opencart.com/index.php?route=marketplace/extension/info&extension_id=41838&filter_search=recaptcha .
The module is installed, modified, reCAPTCHA v3 keys set. However, the SCORE field is not displayed.
