Where is the content cache when using apply_filters(‘the_content…?

I’m unable to replicate the problem you’re describing. I’m guessing it has to do with one of two things:

An issue with $sections – how exactly is this populated?

or

A hook to 'the_content' somewhere else in your code – perhaps a filter function you wrote has a bug in it causing the duplicate content?
