Excel windows and mac.

I have a workbook with this formula in one of the cells im on a Windows computer:

=TEXTJOIN(", ",TRUE,FILTER($B$27:$B$60,ISNUMBER(SEARCH(", "&B62&", ",", "&$R$27:$R$60&", ")),""))

I need to send this file to colleagues for them to complete it. Half of the team is mac the other pc. when they save on their macbook then send it back. the formula is now:

=_2__xlfn.TEXTJOIN(", ",TRUE,_1__xlfn._xlws.FILTER($B$27:$B$60,ISNUMBER(SEARCH(", "&B62&", ",", "&$R$27:$R$60&", ")),""))

I dont know why this happens. If anyone has a clue it would be appreciated.

Thanks
