deleting files problem

When I try to delete my corrupt files, bitcomet still says 100% of the file is there. Even when I remove the file from the bin bitcomet says 100%. I try to close bitcomet and restart it, and it still says 100%. I untick the file, close bitcomet, and open bitcomet again. Still it says 100%. Then it creates a new empty file. Do I really have to reboot for bitcomet to understand it doesn’t have the fking file, because it fked up while downloading it?
