Content Type settings inside a sub-site are going to be ignored, and it will use the parent content type settings

Question

I have an enterprise site collection with the following content type settings inside the list content type (columns such as security, document type, etc as required):-
Then I have created a new sub-site of type enterprise wiki, the default list content type for the subsite will look as follow which have the columns such as security, document type as optional :-
But now if I went to the sub-site and I chose to create a new page, and i leave all the columns empty, then the system will raise an error that the columns such as; security, document type, etc are required. although inside the sub-site content type the
columns are defined as optional. So seems that the wiki page inside the sub-site is referencing the parent content type and not its own sub-site content type.
Can anyone advice on this please ?

Hi John,
I tested the same scenario per your post, however the columns retained the same settings in sub-site in the same content type.
I recommend to verify the things below:
Was the content type you used for creating the page the one created in the parent site?
Did you create another content type in sub-site based on the one created in parent site? I recommend to click the column name to go inside the column settings and then check if the Optional is selected. If yes,
 change it and click OK, then change it back to Optional again to see if the issue still occurs.
Best regards.

1. no
2. no. i did not create any content type. i have just create a new subsite of type enterprise wiki , and the content type settings will be same as the parent content type, which have all these columns set as optional. but seems these settings will be ignored
as these columns will raise an error if i leave them empty. so seems that the subsite's library will use the same settings as its parent site collection library, which have these columns set as required...
so i have the following , to make things clearer:-
1. inside the site collection , the content type at the site collection level have these columns as optional.
2. inside the site collection's library the  list content type copy, have these columns as required.
3. on the subsite list content type copy, i have these columns as optional. but these columns on the subsite library will be treated as required columns ...
