Widget Blog

I successfully hid my “Blog Subscribe” widget from the static home page and want it to ONLY show on the actual Blog page right sidebar. I went into the Appearance, Widgets, Manage in Customizer, Main Sidebar, Blog Subscriptions and Visibility, and enabled “Show If PAGE is BLOG” and it does NOT show up on my BLOG PAGE sidebar (or anywhere else, which is the good news). I am wondering if this is a contradiction with a JetPack Plugin as it is a JetPack Blog Subscribe function. Any advice? http://www.JanDeelstra.com
Thanks in advance.
