Craig Rogers there is a file under root/monitorHUDs 

if you edit the monitorHUD.grids with a text editor and find this Section 

monitorGrid 1.0 -1
    {
        name "Timecode info" ;
        units "normalised" ;
        textSizeBase 1080.0 ;
        burnInTextScale 1.5 ;
        textFont "Arial" ;
        color 1.0 1.0 1.0 1.0 ;
        bgColor 0, 0, 0, 0.2 ;

        anchor "bottom" "left" ;
        origin "top" "left" ;
        textSize 15.0 ;

textSize 20.0 ;
        text .03 .10 "Src   TC: ##srcTimeTimecode" ;
        text .22 .10 "Frame: ##srcTimeFrames" ;        
        text .03 .14 "Rec  TC: ##recTimeTimecode" ;        
        text .22 .14 "Frame: ##recTimeFrames" ;
        text .03 .18 "Orig Src TC: ##originalSrcTimeTimecode" ;
        text .03 .22 "Orig Tape : ##srcOriginalTape" ;
 

And change the Value ,22 to ,25 and I think you will be fine 

 textSize 20.0 ;
        text .03 .10 "Src   TC: ##srcTimeTimecode" ;
        text .25 .10 "Frame: ##srcTimeFrames" ;        
        text .03 .14 "Rec  TC: ##recTimeTimecode" ;        
        text .25 .14 "Frame: ##recTimeFrames" ;

I think this HUD when exporting for some reason using a 16/9 scaling
