Design problemp

I designed this in easel and combined all not realizing that I had this extra bar hanging out there. Can anyone tell me if there is a way I can delete this bar now without having to re create my whole design?

Make a square over it end set it’s cutting depth to zero make sure it is in the foreground so it overlaps the part you don’t want, then mark all objects and combine them again all what is under objects with cutting depth zero should be gone.
