Can't add a CCB

[chadg]

I'm trying to add a CCB to my visual.  I used the wizzard and that was pretty easy.  It created two fixtures of 50 pixels each.  Nice.  Now I can't run it and get a compile error that there is a duplicate pixel.  It says that the second fixture shoudl have a start pixel of at least 2 or greater.  OK, fine.  I set that to 2.  Then it erorrs out with the same error, now the fixtures are swapped and it tells me the first one needs to have a start pixel of at least 3.  What gives?  This is very confusing......

 

Any help much appricated.
