Scripts are moved to header

Hello,

while optimizing one of my sites using your plugin, I found out, that all the scripts are getting moved to header. To further explain my situation, here is what I did:

1. In theme child’s functions.php, all my scripts are loaded in footer (in_footer parameter is set to true)
2. wp_footer() gets called just before the closing </body> tag and right before this call I’ve got a “<!– W3TC-include-js-head –>” tag.

So, by my knowledge, this should be enough to remove scripts out of head tag but this is not the case since I still have PageSpeed Insight messages about blocking scripts.

What am I doing wrong?

Also, 1 more question: is it possible to combine all my scripts into one script to reduce number of requests being made to server?

Thank you in advance
