Unsecure connection when switching to Customize using Sydney Pro

Hello,
I have noticed that I loose a secure connection when I switch to “customize” with Sydney Pro. I had to uninstall the recommended Crelly Slider because it switched the admin area to ‘not-secure’ connection. At this point I am not sure if it is Sydney, the Slider, or WordPress; however, since the Slider is uninstalled and I get the same ‘not-secure’ connection with Sydney when switching to “customize” it’s either Sydney or WordPress 4.7.2?

However, I it seems that I don’t have the same issue after installing the WP2017 theme and switching to ‘customize’?

Anyone else reported this issue?
Thanks,
Cas
