I have always thought the loaded tags and symbols from the annotate ribbon was a good place to set the default tag used in the project if there are multiple types. However, recently I discovered, using the create similar command changes what is set in this dialog!

Is this right? Why does a command in Revit affect this table of settings? Just trying to understand the thinking behind it (or am i seeing something weird?)

While I am asking about this dialog, why when I create a new sheet, is the default selection not what is set in this 'Loaded Tags & Symbols' dialog?
