The comments are removed. And I was pretty sure the metas were removed, but I did more testing on multiple sites after seeing your reply, and now I don't think the metas are removed, but there is still something strange going on.
What prompted the original comment was no posts except for 1 were indexed by Google after having submitted a sitemap for more than a week. The 1 post that was indexed did not have the meta description set in the post.
I turned off HTML minification, and the next day all posts were in Google with the right metas.
On closer examination between the 2 sites today, on the troublesome site, the metas break where meta is on one line and the value (such as name='description') is consistently on the next line. I don't know why it is breaking that way, but could that have been the reason Google couldn't see the metas?
And I am fairly certain that the original tests I conducted did not have the metas in the page source, but now, after turning on HTML minification again and redoing the tests, they're there as I described.
