GRIDLINES: I CANNOT REPEAT THE SAME LETTER

[qddmonterde]

Hi! I need help. It is said here in the error that the name entered is already in use. Enter a unique name. In the screenshot, I supposed to put letter "A" to the next building. But an error appeared.

As the error message says - the letter A is likely been used already?

This is Grids and you can not use the same name for two different grids.use A' or A1 or AA or etc.
