Problem with registrations

Hi Guys

Joomla 3.8.8
CB 2.1.4
antispam plugin 3.1.0

I have a couple of problems with registration
I get a lot of fake registrations, despite that I've disabled Joomla's own registration, and only allow it through CB.
CB is protected by antispam plugin.
I'm currently using the 'internal code' setting, it was set to 4, I've increased it to 8.

I've tried with the questions, but as far as I can tell, it only uses the first question. Question block is created like this:
A question?=An answer\r\nAnother question?=Another answer\r\n
That should be correct, right?

I can't use the math setting, as the 'arithmetic' operators are not translated to danish.

I've gone with the recaptcha v2, but I really don't like that one.

For all of them, it happens that if I don't answer the question, the page refreshes, but only shows the 'name' field in the registration form?

Each question and answer block should be separated by a linebreak. Don't manually add \r\n, simply press Enter/Return. So you'd have the following.

A question?=An answer
Another question?=Another answer

You can translate them. All the non-integer based parts of the math captcha are passed through translations. So for example to translate "add" you'd have a language override as follows.

Key: add
String: ADD

The math question language string is as follows.

Key: CAPTCHA_MATH_EQUATION
String:

Please ensure you've the latest CB build and CB AntiSpam build installed and retry. I'm not seeing any such issue in my tests.

With the upgrade to 2.2.0 it seems to be mostly solved, still one a bit odd thing,
When I go to the mainpage, the login box looks like this:

When I go to the registration page, the login box looks like this:

So somehow the CSS is affected by showing the registration page?

CB doesn't apply its CSS to the login module as it's meant to be styled by your template. Right click and inspect element on the password field to open your browsers developer tools then review the CSS on the password input to see why it's shifting down. I'm guessing it has a margin being added by something.
