AMP Script Issues

I’m checking AMP issues on Google Search Console and I don’t know how to solve the next ones:

1.There are scripts in the page using different release versions.

On page detail the issue is The script version for 'amp-iframe' is a unknown version which mismatches with the first script ...:

Some pages with the issues are:

2. Custom JavaScript is not allowed.

On page detail the issues are:
The parent tag of tag 'amp-iframe v1.0 extension script' is 'body', but it can only be 'head'.
The parent tag of tag 'amp-bind extension script' is 'body', but it can only be 'head'.

Some pages with the issues are:

3. Only amp-boilerplate and amp-custom 'style' tags are allowed, and only in the document head.

On page detail the issue is:
The parent tag of tag 'style amp-custom' is 'body', but it can only be 'head'.

Some pages with the issues are:
https://www.zuckermanlaw.com/defense-contractor-whistleblower-protection-verdict/
https://www.zuckermanlaw.com/sp_faq/can-sue-individual-sarbanes-oxley-act/
https://www.zuckermanlaw.com/sp_faq/what-is-sexual-harassment/amp/

Each issue seems to be related with scripts in the header. Checking others support answers I found that the scripts described on the issues are properly added I don’t understand the source of the issues.

Thank you for your help in advance.
