Annoying dock in Ubuntu 17.10

Question

today I upgraded to Ubuntu 17.10 from Ubuntu GNOME 17.04 and the dock started to have really strange acting. First of all, I am a beginner in Linux. I am using Ubuntu GNOME and dash to dock extension, but after upgrade to 17.10 other dock started to appear even on locked screen: Dock on locked screen

and also here: Dock on password entry

and most annoying the dock is when I maximize app: Dock on maximized apps

I think it's the dock from old Unity GUI but I don't want to be there and I cannot find

1. settings for the dock to somehow disable/hide it
2. package name to uninstall it
   

Please help because I want to use old dash to dock extension
Thanks

Uninstall Ubuntu Dock

• Open the terminal and run these commands:

$ sudo apt-get remove gnome-shell-extension-ubuntu-dock
$ rm -rf ~/.local/share/gnome-shell/extensions/dash-to-dock@micxgx.gmail.com

• Reboot.

Install Dash to Dock

• Go to https://extensions.gnome.org/extension/307/dash-to-dock/ and install the extension by clicking on the On/Off button. You might need to install Firefox or Chrome GNOME extensions plugin
