Formatting Issues with 2.04

Problem/Motivation

We upgraded our site to v2 and have many issues with the theme. I'm sure this is due to configurations but v1 worked fine.

We installed 2.04 per instructions and created a subtheme. Currently, the primary 2.04 is default. If we use "Green" color theme which we used under v1 user screens are fine. If we try to change color theme screens are scrambled, menus do not work and no colors appear. In addition, all administrative screens (default is Seven theme) are scrambled.

Steps to reproduce

Original v1 site everything worked fine for testing.

Upgraded site site01 with color set to v1 "Green" ok. However, edit screens missing information.

Change color to "Red" menus do not collapse, formatting is all gone, colors do not respond or work. All admin screens are scrambled.

One other thing which we do not know if it contributed is this site was cloned per our sysop:

1. The process we used is here: https://drupalize.me/tutorial/how-clone-drupal-8-site-without-command-li...
2. Copied files, made duplicate of database, changed settings in settings.php to point to the duplicate database, created domain to point to new site path.
3. Used composer under new site path to install latest theme.
4. I did not do a configuration import as we want this site to have it's own configuration.
