Cannot delete translation memory from GroupShare 2017

Question

Hi all, 
 I'm trying to delete a translation memory from GroupShare 2017 using the web interface but get the following error message: 
 "Translation Memory was not removed.

Error: System - Value cannot be null. Parameter name: tmId (details: System.ArgumentNullException: Value cannot be null. Parameter name: tmId at Sdl.LanguagePlatform.TranslationMemoryImpl.API.DeleteTranslationMemory(Container container, PersistentObjectToken tmId))" 
 
 I'm hoping that someone from SDL is monitoring this group, but in my experience they're not. So anyone else out there who's seen (and solved) this issue? 
 
 Regards, 
 Henk
