Set Stargate Address

Hey, I am no noob at Stargate Ive used it in the past but recently i tried to set the address of a Stargate and I cant seem to work it out. I put in address say “ABCDE” or "ABC’ and it just constantly says editing next to the field. Is there a way to save it? Thanks

They have 6 letter and or number addresses.
Examples:

Gate1: 123456
Gate2: mo0vi3

v -i knew i had forgotten to say something!

After you’ve entered 6 letters/numbers into the text box, it will say “saved” (or something similar).
