altered setting in contacts list please help

[yakfire]

I went into my contacts list to send a text and accidentally changed a setting but now i have no idea how to change it back. in the contacts list it show the option to text or call a contact without having to go into the contacts details however i have somehow changed a setting so that i have to swipe either right or left to show the text/call option for each contact, is there anyway of changing this back? thanks
