Conditional formatting not saved / how to copy rule on different line

Hello!

I have this file that I created and I had manually created the CONDITIONAL FORMATTING line by line so that besides the numbers I enter in each column for the monthly sales for each code would have a little red/yellow/green icon beside each entry that would give me a visual if the number of cases sold per month was higher/lower or matches the calculated AVERAGE monthly sales Cell P.

I did all 153 lines one by one, but after I saved the file and tested it, I got some rows that kept the formatting and others that didn't.

Also, is there a way to copy the rule for CONDITIONNAL FORMATTING to all the lines without having to create the rule one by one.

I need the rule for example for Line # 7 to take into consideration the calculation (based on my formula saved in cell P7).
The CONDITIONAL FORMATTING I selected:

CONDITIONAL FORMATTING
NEW RULE
FORMAT STYLE: ICON SETS
ICON STYLE: SELECTED THE ICONS I WANT WITH 3 DIFFERENT COLORS
GREEN: WHEN VALUE IS >= =$P$7 TYPE FORMULA
YELLOW WEN < FORMULA AND > =$P$7 TYPE FORMULA
RED WHEN <= FORMULA

When copying the same format on the line below I need it to be :
GREEN: WHEN VALUE IS >= =$P$8 TYPE FORMULA
YELLOW WEN < FORMULA AND > =$P$8 TYPE FORMULA
RED WHEN <= FORMULA

How can this be done?

Thank you for your help!
Greatly appreciated!
