I am currently on CMS 12.1.0
I had properties defined in code for pages / blocks, when removing the properties from code, I cant then go into Admin mode to delete the property. When looking at the model via Admin mode it still thinks its "From Code" and cant find the Delete option.
Is this a bug with CMS or am i missing something in config
