Issue using htaccess to redirect to main domain's subdir for everything except specific subdomains (and subdirs)

Question

Currently we have an htaccess setup using the below settings;

RewriteCond %{HTTP_HOST} !^(staged|foobar)\.example\.com$ [NC]
RewriteCond %{REQUEST_URI} !/(Press_Kits|logos|admin|console|shop)/ [NC] 
RewriteRule ^(.*)$ https://www.example.com/shop/$1 [L,R=302]

The goal of it is to have most to all traffic to direct to https://example.com/shop/, but to allow access to the subdirectories like https://example.com/logos/, etc. This all works well for the most part. The issue lies where we are now trying to duplicate the shop for a staging environment and set that to https://staged.example.com which going to that domain will work with the above htaccess settings as well, however getting to the backend of the shop using the subdirectory location of https://staged.example.com/admin redirects to the main dir's shop.

So https://staged.example.com works, but https://staged.example.com/admin doesn't work, and redirects to https://example.com/shop/admin .. I've gone into the database to redirect all the SQL settings for the shop to be pointing to the staged subdomain, so I'm at a loss as to what causes the redirect back to the main store.

The subdomain doesn't have any redirects in place to retain everything within the subdomain, so would that be something I have to add on the subdomains side? Is there another/change I need to make on the current conditions to allow not only for the subdomain but also the subdomains subdirectories?

Any ideas? Thanks!
