Alternate page with proper canonical tag

If I want to say more about my problem, I should explain that these URLs are from our old CMS, joomla. It’s almost 2 years that we have migrated to wordpress. But recently (Even yesterday) google shows some URLs like this in Alternate page with proper canonical tag search console.

mysite.com/cat1/post1/?format=feed&type=rss
mysite.com/cat1/post1/#!/ccomment

I don’t have these URLs on my site right now but if I add
?format=feed&type=rss
at the end of any URL that URL will be work. Yoast has canonical tag for mysite.com/cat1/post1/?format=feed&type=rss url and this caused a lot of URLS with this error for me.

When I inspect mysite.com/cat1/post1/?format=feed&type=rss in search console the resualt is as below.

Infact I need to show google that I dont have these URLs any more, but I don’t know how to do that with Yoast. Can you help me?

Hello @saraeee

Thanks for reaching out regarding your page indexing report from Google Search Console. Please see what’s in the documentation:

Alternate page with proper canonical tag
This page is marked as an?alternate?of another page (that is, an AMP page with a desktop canonical, or a mobile version of a desktop?canonical, or the desktop version of a mobile canonical). This page correctly points to the canonical page, which is indexed, so there is nothing you need to do. Alternate language pages are not detected by the Search Console.

Furthermore, WordPress outputs your content in different formats across different URLs (like RSS feeds of your posts and categories). It’s generally good practice to disable the formats you’re not actively using. So we have a feature in?WordPress > Yoast SEO > Settings > Advanced > Crawl Optimization > Disable unwanted content formats.?
