Tag stuff once and don't have to change it later.
Somehow, unbeknownst to you, the default tag has been set to some random format. You can't change the tag type as you are tagging items. Only a few properties can be changed as you go.
You want that tag to show up right the first time you create it, so if it's wrong - fix it. You can change the default tags in two ways. The first is right before you tag your item. Start by checking Tag from the project browser, or use the TG shortcut.
Now, before selecting your item hit the Tags… button.
This will bring up the default tag menu.
Now you can change the default for any of your items, or load in a different tag for one of them.
The other way to get to this menu is through the Settings menu at the top of the window. Scroll down to Annotations and select Loaded Tags.
