Remove percentages from robocopy log

I'm using an older version of robocopy that includes percentages in the log even if the /NJH and /NJS paramters are set. So I'd like to remove the percentages from the log:

            72880735    H:\1.txt
100%  
            33038490    H:\10.txt
100%  
            64878348    H:\2.txt
100%  
            25875810    H:\3.txt
  0%  
100%  

I've tried with

(Get-Content $logfile) | Where-Object {
    $_ -match '[\s](\d{1,})(\s+)(\w\W\W.+)'
} | Set-Content $logfile

But that results in

            72880735    H:\1.txt
            33038490    H:\10.txt 
            64878348    H:\2.txt
            25875810    H:\3.txt
  0%  

So I get the 100%'s stripped out, but not the 0%.
