Number of Components (Y Cb Cr)

Hi everybody!
I am using ImagJ for an year for batch picture processing. Recently I started shearing this with my colleague. And i found that after running the same macros we obtain same picture but (!) mine have 1 Component (Y). And for her it is 3 Components (Y Cb Cr).

What should we change to make her pictures being 1-Component??
This is essential for me because 3 -component pictures cannot be processed further.
The version of ImageJ is the same for us.

Macros for batch processing are usually like this:

run("RGB Stack");
run("Stack to Images");
selectWindow("Red");
//run("Brightness/Contrast...");
setMinAndMax(160, 255);
run("Apply LUT");
setOption("BlackBackground", false);
run("Make Binary");
run("Invert");

Properties file of her and mine pics:
