Cache issue even in incognito mode

I have a weird issue lately, I have made a couple of changes in the homepage layout, deleted few blocks but they still appear in incognito mode.

I have tried everything, even uninstalled Hummingbird and then reinstalled. had my server restarted as well.

The changes are seen when I am logged in, but in incognito mode like a visitor is visintg the changes are not seen.
