This issue happened to Gantry core particle (Joomla articles) too. You can follow the working process by Gantry team here https://github.com/gantry/gantry5
New V5.5 feature https://github.com/gantry/gantry5/tree/feature/v5.5.0
Gantry5 future plans https://github.com/gantry/gantry5/issues/2789
Again, Please stay with Joomla 3.10 at the moment 🙂
Thank you
