Post cache cannot be cleared

Hello
Check “Clear cache files when a post or page is updated”
Post cache is not cleared after updating post
(Only tag and category cache is cleared)
Click “Clear Cache of This Page”
Or
https://www.wpfastestcache.com/features/hide-clear-cache-button/
Also has no effect
I manually delete the cache from FTP or delete all caches is valid.
Can solve this problem?
