Blog Feed broken

I ran a fresh install of the most current Dev (8.x-2.x-dev, 27-Feb-16).

I went into Structure->Views->Latest Blog Posts (edit), and selected the "Latest Blog Teasers Feed". That displays:

<?xml version="1.0" encoding="utf-8" ?>
<rss version="2.0" xml:base="http://bootcampwy.org/blog/feed?field_blog_topic_target_id=All&amp;=Apply" xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:content="http://purl.org/rss/1.0/modules/content/" xmlns:foaf="http://xmlns.com/foaf/0.1/" xmlns:og="http://ogp.me/ns#" xmlns:rdfs="http://www.w3.org/2000/01/rdf-schema#" xmlns:schema="http://schema.org/" xmlns:sioc="http://rdfs.org/sioc/ns#" xmlns:sioct="http://rdfs.org/sioc/types#" xmlns:skos="http://www.w3.org/2004/02/skos/core#" xmlns:xsd="http://www.w3.org/2001/XMLSchema#">
  <channel>
    <title>Latest Blog Posts</title>
    <link>http://bootcampwy.org/blog/feed?field_blog_topic_target_id=All&amp;=Apply</link>
    <description></description>
    <language>en</language>
...
</rss>

(BTW, the default code does pass the RSS feed validator @ https://validator.w3.org/feed/ but does have some namespace recommendations ... but that's a non-issue)

So if I point my browser to the path (in my case bootcampwy.org/blog/feed .. I get the following:

http://bootcampwy.org/blog/feed?field_blog_topic_target_id=All&=Apply en

and NOT the actual RSS XML.

This is also the case with the blog archives. (it replys with: http://bootcampwy.org/blog/archives/feed en instead)

What do I need to change to make this work properly?
