Good Day Arnold,
Thanks for your post.
To make changes to multiple doors of the same type, select the door edit tool and left-click first door. Now hold down Ctrl, and continue left click each door that you want to change. Once all doors of this type have been selected, whatever you edit in the attributes will update all doors (including if you were to change the door type).
Can you please try this and let me know how it goes for you?
