[Hummingbird Pro] Meta values save as non-https

Hi,

Website console was throwing notice of mixed http/https content within the site and when i checked the database table postmeta to see the non https links it seems that the values belongs to humming bird pro compression.

E.g. _handle_urls a:1:{s:10:”divi-style”;s:68:”http://bmcdevelop.wpengine.com/wp-content/themes/webminds/style.css”;}

We are sure that previously these were on https as we did a search and replace to all the non http links. After uncompressing and clearing cache from the plugin the meta values with non https are gone.

Just want to see your insights with regards this issue.

Thank you
