Issue with Timeline slicer week selection - for Fiscal Year implementation

Same here. I used a debugger to find out, that there are at least 3 functions for the label generation (Month, Quarter and Year).

The functions look like: 

n.prototype.generateLabel = function(e) {
  var t = this.shortMonthName(e.startDate) + " " + e.startDate.getDate() + " - " + e.year;
  return {
    title: t,
    text: e.startDate.getDate().toString(),
    id: e.index
  }
}

n.prototype.generateLabel = function(e) {
  var t = this.quarterText(e.startDate);
  return {
    title: t + " " + e.year,
    text: t,
    id: e.index
  }
}


n.prototype.generateLabel = function(e) {
  return {
    title: "Year " + e.year,
    text: e.year.toString(),
    id: e.index
  }
}

As pbiviz files basically are zip files, I decided to download the visual, unzipped it and edtited the code file. 

I thought, that replacing

 e.year

by 

(e.StartDate.getMonth() == 0 && e.StartDate.getDate() == 1)? e.year : e.year+1)

should work (at least for fiscalyears, that dont start at January 1st). 

But somehow it seems that this has no effect. After i zipped the files and imported the modified version, I didnt see any change. Is there something like a visal cache?
