Data Asset Not Showing Up

hi. i am following the unreal engine 4 blueprint vehicle user guide. i have done everything up to the part where you assign the tireconfig data asset to the wheel blueprint. when i click none next to tire config and look for the data asset it does not show up. tried searching for it and also dragging it from the content browser to there, checking and unchecking boxes under view options and tried using tiretype instead. how can i get this to show up? thanks

bumping the question.
