Just started using my Raspberry Pi now that school is out. I connected the T-shaped cobbler and I was following a few different tutorials to get used to the GPIO set up. I began to notice that when ever the LED was connected to ground and certain pins it began to glow (some times faintly other times very brightly depending on the pin) not sure exactly what is going on. I was using a 470Ω resistor.
This is one tutorial I was following:

I also set up and started (I think) wiringPi because one of the projects I initially tried said it was necessary and I was following the steps.

I am new to all of this so any help is appreciated I am trying to learn and tinker as much as possible with my time off.
Thank you in advance for any help!
