After a few hous of clearing the cache some pages get cached in apache

 HTTP/1.1 200 OK

Why Is apache caching a text/html if this content type is not defined as
ExpiresByType?

The cache can also key off the Last-Modified date to determine
freshness.  See the directive CachLastModifiedFactor.  That doesn't,
of course, explain why it would be caching explicitly expired content.

I suggest moving to 2.2, where mod_cache* is no longer experimental.
Much improvement has been made between 2.0 and 2.2.
