Conditional Format "Applies To" Changes, Don't Want it To

Hello,

So I have a conditional formula that highlights blank cells in 5 columns (D,E,G,H,I) if the reference column (B) has an entry. The "Applies To" columns in the formatting rule are absolute references, and the rule works the way it should....

However, I was working in column K: if I add text, enter and delete it the cell is automatically highlighted; and when I checked the conditional format rule, that cell is now added to the "Applies To" field.

Why is this happening? And more importantly, how do I stop it?

Thanks for the help.

EDIT: I just realized another thing.. this only happens to the cells that have no blank cells in any of the columns mentioned above.
