Removing position filter from a user created view

Hi,

We have a view in the Location Planning workbook where we have defined a position filter on the location hierarchy through configuration. We have a new view created from the front end which is the copy of the existing one. This view also has the position query which we want to remove. Now since this view was created from front end, we do not have this updated in our configuration and hence we are not able to remove it. Is there any other way of removing the position filter from frond end /back end ?  

Thanks,
