c# - MODI OCR Text reading issue

Question

I'm using MODI to read the text in scanned images and do some further parsing based on what I find in the text. However, sometimes it doesn't read the text properly. For example: If I have just the text "GroupScan" in the image, it reads it sometimes as "GroupScan", sometimes as "Gr0upScan" and sometimes as "roupScan". I have no clue as to what can cause this. Here's my code:

 MODI.Image image = (MODI.Image)md.Images[0];

 if (image.Layout.Text.ToLower().Contains("groupscan"))
 {
    groupScan = true;
 }

Any help would be appreciated.

Thank you.
