That method overwrites the previous file because what it is doing is only doing this:...
if (/orange/i.test(this.documentFileName)) {
this.info.Title = /orange/i.test(this.documentFileName.replace(/\.pdf$/i,""))
} else if (/banana/i.test(this.documentFileName)) {
this.info.Title = /banana/i.test(this.documentFileName.replace(/\.pdf$/i,""))
}
