Can′t disable the bulk tagging process

Hello Devtard, thanks again for this plugin… I am having an issue now, everytime I try to stop the bulk tagging, it says :

Recurring bulk tagging event has been unscheduled.

However, at the right side of the screen, it says

Scheduled bulk tagging: In progress

and if I clik on “proccess posts now” it says :

Error: The bulk tagging tool couldn’t be run, because a scheduled bulk tagging event is currently in progress.

What can I do? Thanks
