Wrong file size after and saved

[lusiakpurnama]

I'm using gulp-css-purge v3.0.9. In package-lock.json css-purge installed is v3.1.8.
When I use the verbose options, it gives me:

Before: 382.765KB
After: 0.33931KB
Saved: 382.4257KB (99.91%)

But the file after purged is 339KB, not 0.339KB

Same here.
Before: 565.296KB
After: 0.283115KB
Saved: 565.0129KB (99.95%)
