You have to provide a minimal example, in the following the example the text within the frame isn't indented.

I cannot always provide a minimal example (how much I would like to) as my TeX is produced in a pipeline from 5600 lines of lua and METAPOST code.

But luckily, in this case I can, the one using \phrasetext is indented, the other one is not.:

\setuplanguage[en][patterns={en}]\mainlanguage[en]

\definelabelclass[phrase]

\setupphrasetext[en][metamodelexplanation=  {...}]
