Contact Form 7 – Error keeps appearing even when fields are filled

Hello,

On our website we offer different tools, at every tool-page we have the same problem.
When I fill in the fields that are required, it still gives an error that you need to fill in the fields. Even if I fill in the fields that are not required, it doesn’t work.

So now my visitors cannot download our tools and we miss conversions.

The code that I use in the contact form is:

<label><b> Name * </b>
    [text* your-name] </label>

<label><b> Company name</b>
    [text your-company] </label>

<label><b> Phone number</b>
[tel tel-922]</label>

<label><b> E-mail * </b>
    [email* your-email] </label>

[checkbox* Consent-6 use_label_element " "] <span style="font-size:65%;color:#F5F5F5"> I accept the </span> <a href="/terms-and-conditions/" target="_blank" style="font-size:65%;"> terms & conditions</a> <span style="font-size:65%;color:#F5F5F5"> and </span> <a href="/privacy-policy/" target="_blank" style="font-size:65%;"> privacy policy </a><span style="font-size:65%;color:#F5F5F5">*</span>
