Newsblur not reading all content from some feeds

problem
#1

Newsblur is only sporadically updating articles from 2 blogs. The examples are are:
https://www.armstrongeconomics.com/feed/
https://survivalblog.com/feed/

If a blog has 6 posts in a day, Newsblur might pick up one or two, or maybe none.

This issue occurs on Windows/ Chrome browser and on the iOS app.
