How to hide progress bars in PCManFM 1.2.5?

I am having some problem with the PCManFM on my Lubuntu 18.04LTS. The “Copying Files” progress bar always appears on top of the viewer so everytime I want to navigate through the files I need to move it out the way, it won’t let me hide it without hiding the viewer. I have my own reason that I need to search through the files while transfering files via FTP.

Since I don’t have much experience with linux I don’t know if there is any command or scripts that can do the job eventhough I would like to learn more about it. If it is just the nature of this FM I might consider changing to another lightweight one.
