d8 WAMP Virtual Host works, but links are wrong? (no replies)

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 (with the drupal8 folder in the url)

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
</Directory>
</VirtualHost>

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