Conditional Formatting Gone Mad

This is CF I used on my Excel 3013 planner spreadsheet.
Day one - as it should beAfter only 2 days of adding and dragging text around, look what happens to my CF.
I am referring in particular to the horizontal orange & purple line formatting.
(A second CF for the orange line has been created).

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

it is because you inserted lines or deleted some while in the mits of CF. don't worry about it simply if the region is E:E and S:S simply put this back =$E:$E,$S:$S copy paste there and it should be fine.

Every time you insert/delete rows or columns or copy/paste with formatting Excel has to try and figure out how to handle conditional format rules and it's quite rubbish at it so this is, i'm afraid, fairly normal for any sheet that uses more than a few simple CF in a limited range of cells.

One way to improve it is to use 'paste special, merging cf' which stops some, but not all,  of the complexity excel will add over time. Another is to remove all the rules and add them back in from a template (using format painter) once document editing reaches a natural stopping point (just before publishing a report for example).

Here's an article with tips on what to look for to improve it but I'm not aware of anything that will resolve it completely:
