Reporting a post as spam

I just now reported the below post "Air cooled heater exchanger", but received this error message.

Error

No query results for model [FluentCommunity\App\Models\Feed] 8078

Btw I posted this in the general space. I see that below post I reported is in FluentCommunity space. So I wanted to also edit my comment and change it from the general space to the FluentCommunity space but it looks like after publishing a post one can not change the space it is posted into.
