Can no longer save edits to SQL for models

I can no longer save edits to the SQL code from models that I created. This stopped working around the same time my permissions were elevated to Admin.

What do you mean exactly? You cannot update models based on SQL?

I created a model using the native query option. After a few days I went back to try to make a few changes to the SQL code in the model's query, but it will not let me save the changes. I says I do not have permission, but I have admin privileges in our Metabase installation. Trying to figure out why it won't let me make edits to that models SQL code any more.
