RPI GPIO Ports default on?

Question

My LEDS connected to ports CE1 and CE0 are automatically on at startup. Is this normal? I have included a code that turns them all off when I run the script.

Yes, it is normal.

GPIO 0-8 have their internal pulls to 3V3 enabled at boot. That will allow enough current to flow to dimly light a LED.
