v4 with 2 races - image thumbnail in place of sig?

[Awais Tahir]

Hi,
Im using v4 branch.. Ive recently added another race in my config file and ran the program.
every image created for the second race have the same image thumbnail on left side upper corner of the image.
Ive commented out the signature part of the code but still having the same issue.

Race 1 is working fine, but Race 2 have thumbnails.

anyone using this with multiple races facing similar issue?
Thanks.
