Had the problem on my map too blue spawning in reds spawn - even though it said the red blue thing.
Will give you the coding when I go home basically it's like this:
Spawn room - red or blue
Team Red or Blue
Associated_CP point (or something like this and what I have to check) enter in the name of the 1st CP - if red and the last CP if blue or vice versa.
Round ... A, B, C, etc name it
When you name both the round and yhe associated spawn point you will always spawn at the right strating point 0-)
