Thanks for the response, Emily. It’s not a permissions issue as this occurs with an account with access to view/modify all. I did find this, however, regarding the limitations of save/cancel buttons on the page title component:

I added a global action to the top level table to save all models. But after further testing, the save button in the page title seems to be working now. Strange, but at least it’s working. Just hope it stays that way
