Circuit diagram shows a 10nF capacitor alone on an input pin of 4093 AND gate. Something is missing there.
Also AND gate on e signal is not necessary.

You are still connecting logic inputs after 470Ω resistors loaded by LEDs. This is still a NO-NO because you are going to get marginal logic voltages.

that worked!:>>> tysm! i tried to check the push buttons' output using led then it fixes it now the 7 segment counts. tho I tried to connect the sensor back but it does not count again? help me pls :>>>
What is the part number for the IR sensor? You need to first look at the datasheet for the IR sensor and make sure you understand it.
