d8 WAMP Virtual Host works, but links are wrong?

I have the virtual host “mostly” working on my local machine for www.ustenniscourts.smurm. The domain works, but some links point to www.ustenniscourts.smurm/correctlink and others to www.ustenniscourts.smurm/drupal8/incorrectlink

even on the same page like Appearance

You can place blocks for each theme on the block layout page. (has the unwnated /drupal8/)
But the Settings link for the Themes is correct.

Is this a drupal setting that i am missing?

I have drupal 8.2 installed locally in wamp64/www/drupal8 with
WAMP 3.0.6
Windows 10

Virtual Hosts allowed in httpd.conf

The following in my httpd-vhosts.conf:

<VirtualHost *:80>
	ServerName www.ustenniscourts.smurm
	ServerAlias www.ustenniscourts.smurm
	DocumentRoot c:/wamp64/www/drupal8
	<Directory  "c:/wamp64/www/drupal8">
		Options +Indexes +Includes +FollowSymLinks +MultiViews
		AllowOverride All
		Require local

I have the following in my host file: localhost localhost.com www.ustenniscourts.smurm # drupal8 sandbox
