When you want to delete a training, go to the list of trainings and click on the dropdown menu next to the training and click delete.

 

 

A confirmation box appears. If you are sure click delete, if not click cancel.

 

 

NOTE: Trainings that are deleted, are still in BizzMine. You can find them in the trashcan (you find the trashcan in the list of trainings) and restore them from there.
