Having issues with square brackets for year in OSCOLA style; seems that Zotero is generating round brackets where there is a volume number, regardless of the need sometimes to have square brackets, as in where, 'there is more than one volume in a year'. Per OSCOLA 4th Ed, at pg 13:

'Case citations without neutral citations

The components of a typical case citation without a neutral citation are:

case name | [year] OR (year) | volume | report abbreviation | first page | (court)

As the following example shows, when the year is used to identify the law report volume it is given in square brackets In such cases, also give a volume number if the series in question was issued in more than one volume during that particular year, but do not do so if only one volume was issued.

Page v Smith [1996] AC 155 (HL)

Where the year is necessary to identify the volume and there is more than one volume in a year, give the year in square brackets and the volume number before the report abbreviation, as in the following example from volume two of the 2001 Appeal Cases.

Barrett v Enfield LBC [2001] 2 AC 550 (HL)

Give the year of judgment (not publication) in round brackets when the volumes of the law report series are independently numbered, so that the year of publication is not needed to find the volume.'

Thank you for any help with this!
