ok so I'm building a circuit using a 555 timer and a 4017 decade counter. I have 10 LED connected to the decade counter. What im trying to accomplish is having the first led in line turn on then off then the next one in sequence turns on and so on and so forth. When the last LED is reach the circuit will start from the beginning again non stop. timing is controlled by a 100k pot. What i have now is the circuit turns on and a random LED will turn on. I added a momentary push button to the circuit and if i keep pressing it it will keep randomly selecting LEDs to light, sometimes in rare instance it will light 3 at once. I would appreciate any help i can get in debugging or fixing my issue thanks.
attached is the PDF of the circuit I'm trying to build.
