Xporter Tempo TimeSheets integration not retrieving fields correctly

Description
When exporting Tempo Timesheet fields. The fields retrieve wrong information or none at all. 

#{for worklogs}
   ${Worklogs[n].Author} 
   ${Worklogs[n].AuthorFullName} 
   ${Worklogs[n].Comment}
   ${Worklogs[n].Created}
   ${Worklogs[n].CreatedDate}
   ${Worklogs[n].CreatedDateTime}
   ${dateformat("dd-MM-yyyy HH:mm:ss"):Worklogs[n].StartDate}
   ${dateformat("dd-MM-yyyy HH:mm:ss"):Worklogs[n].Date Started}
   ${dateformat("dd-MM-yyyy HH:mm:ss"):Worklogs[n].StartDateTime} 
   ${Worklogs[n].Time Spent}
   ${Worklogs[n].TimeSpent}
   ${Worklogs[n].TimeSpentFormatted} 
   ${Worklogs[n].BillableSeconds}
#{end}

Pre-conditions
Have the integration with Tempo Timesheet configured (Configuration tutorial)

How to reproduce

1. Go to a issue
2. Log time in Tempo worklogs
3. Export worklogs using Xporter template

Actual result/Attachments
StartDate is not exported in Excel format.
Created, CreatedDate and CreatedDateTime all export the same format.
Comment is not displaying correctly, instead it exports "time-tracking". (should display the description)
Author and AuthorFullName displays Tempo Timsheets as the author.
BillableSeconds is not being exported. 

Expected result
StartDate is exported in Excel format.
Created, CreatedDate and CreatedDateTime all export the format mentioned in the field.
Comment is not used anymore and should be replaced by description.
Author and AuthorFullName displays the user as the author.
BillableSeconds is exported.
