There are several issues with the Tiefling Racial Traits from the Blood of Fiends* sourcebook.
1) The Subrace options should be removed from the Racial Traits. All of these options are handled through selecting the appropriate Tiefling Subrace (Demon, Div, Devil, etc...) and those function properly. These just need to be taken out, since you can't even select them in this menu.
2) The Tiefling Variant Ability option is not available under the Racial Traits. It looks like they are all listed appropriately under the "Tiefling Variant Ability" menu, but you have no access to it. It should be functionally similar to the Aasimar Variant Ability options, which require you to take the Variant Ability under the Racial Traits, and then select from the Aasimar Variant Ability lists.
