Unexpected formatting of in-text citations

EndNote EndNote How To
1

I’m a new user of EndNote X9. I’m working with the British version of the Harvard citation style, under which most citations follow the template Author (2023), but laws should be cited as Name of Act 2023 (i.e. without brackets).

This works fine in the biography, where I have modified the template for Statute to:

Name of Act Year, Publisher, Country. |Enacted Date Enacted.

For in-text citations, I have the following templates:

(Author|,0Year)
Author0(Year)

In both cases 0 is actually the little circle symbol that I seem to be unable to type here.

When citing a statute in-text, the first template returns (Name of Act 2023), which is as desired. When using the second template for in-text citations, I get Name of Act 2023). I would like to get rid of the second bracket if possible.

Any suggestions on how this could be accomplished?
