Problem: RSS-Feed contains no descriptions

I recently switched from Blubrry to Podlove and I realized to late, that the RSS-Feed does not contain the descriptions (what in Wordpress just is the text in the article). Looking at another Podlove-installation of mine I realized, that the RSS feed in question does not contain any

< content:encoded >.

I looked at the usual places and checked Debugging but I have no clue what is going on. Does anyone know what might be the mistake? Or what hinders Podlove in generating the correct RSS-feed?

This seems to have been a “Have you tried turning it off and on again?”-Problem…

I toggled “HTML-Inhalte einbeziehen” (Include HTML-content) and now it seems to work. Just in case anyone else has the same problem…
