Can anyone tell me what the folder with the dot means in GL Transaction Type Maintenance?

Can anyone tell me what the folder with the dot means in GL Transaction Type Maintenance?

Modified, right?
I am the only one to ever modify our rules and it is on exactly those ones that I modified.
The underscore as a prefix to his “folder” names would suggest they are not native.
That is what I was thinking but was not positive. Thanks for the reply with the picture!
@jkane The underscore was how CSG did our rules in E9 back before the edited symbol came about, so all of the modified ones were up top.
