On Jacob's profile, you have two identical stickers except with different flag links:
{{Migrating Ancestor
| origin = Germany
| destination = United States of America
| origin-flag = Flags-8.jpg
| destination-flag = US_Flags-6.png}}
{{Migrating Ancestor
| origin = Germany
| destination = United States of America
| origin-flag = Flags.gif
| destination-flag = US_Flags-6.png}}
the problem is in the origination flag, Origination flag "flags-8" is an English flag, whereas origins flag "Flags.giv" is the German flag. Just delete the first sticker and use the second and make sure to use the sticker with the German flag (the top one in this post).
