Old Pi Data writing back to new tag when re-created

Hi all,


I am having a problem with historical data being written back to tags that have been deleted and re-created. Is there a way to remove all previous data that has been input to a tag value? 



Although I have deleted the above PI tag to try and remove the tag "Operation Since Maintenance". The value of 315h comes straight back to the tag when I re-create it. This happens across the board and I can't figure out how to delete all the of the historical data that has been put to the tags. 


I need to ensure that this isn't going to happen before I go ahead an make the 100 or so tags needed.


Please any help!
