File size masks don't work

Searching for files >5G just doesn't work. File size masks in general are broken.

I am using WinSCP Version 5.7.2 (Build 5316)
The protocol I'm using is FTP

Attached is a picture of an example.

Sorry, I can be reached at "awesome3165@gmail.com" if need be.

Thanks for your report.
