4k .R3D doesnt need Render in FCP but 2k does?

[J_Chi]

OK. I am having a wierd problem (i could really use the help guys) I use the 4K Preview .mov and throw that on my FCP timeline and then set the sequence settings codec to REDcode and it works fine and i dont need to render it. But if i start a new sequence and put the 2K preview .mov files on the timeline change the sequence settings to REDcode (just like i did for the 4K) it have the orange render bar. Does anyone know why? I can still preview but why would have the orange bar when the 4k didnt have any? arent they using the same R3D files? I would really appreciate the help if someone knows how to fix this or explain this.

Sorry some more details i need to add are when i add the clips to FCP (F, H, M, or P) i get the render bar and when it asks me about sequence settings i hit yes. but for 4K i still have to go back to command + 0 (sequence settings) and set the codec to REDONE codec. and only with my 4k images i get no render color bars.. but with H M and P i get the orange render bar. does anyone know how to get rid of that orange render bar? or why my F doesnt need rendering but my H M and P does?
