Popup windows in Mint 22.1 not matching theme

[Caverns4]

When using this theme in the newest version of Linux Mint Cinnamon 22.1-Xia, there are some new type of pop-up windows. When selecting Shut Down from the panel or just having to input your password for Root access, there's a new type of Window that shows up that darkens everything behind it, and these new windows do not match the theme at all.

Steps to Reproduce:

• Select the Panel menu and click the Quit button
  or
• Right-click the desktop and select "Open as root"

Intended behavior: The popup windows should have stylized buttons and UI that match the UI around it.
Actual behavior: The popup windows look nothing like the selected theme, distractedly so with flat colors and rounded edges.

Updated, I found this theme on cinnamon-look that is able to theme affected windows. Hope this helps:
