That "<<<<<<< HEAD" stuff is indicative of an unresolved merge conflict. Everything between "<<<<<<< HEAD" and "=======" was from one version of the file, while everything between "=======" and ">>>>>>> origin/master" was from another version of the file. Looking at the history, Chris Jones fixed the roll button for investigation (which was using the lockpicking trained stat by mistake), while Josiah Bradbury (the sheet author) changed the way the roll buttons dealt with the wild die. Then, Josiah merged all changes from the character sheets repo without noticing the merge conflict to the Savage Worlds sheet. The first of those two roll buttons will roll investigation with the variable wild die as designed, but uses the lockpicking trained stat. The second button doesn't have the variable wild die, but uses the investigation training correctly.
