Your rules calculate the difference between two absolute cell references ($O$2-$G$3). If this happens to be larger than 365, all cells in the range $G$3:$G$100001 will be coloured orange.

You need to remove the $ signs from the calculation, thus (O2-O3). Then It might work. Though I'm nor sure as the second pictures isn't clear about which cells we are looking at.

If it still doesn't work, you can perhaps upload a file (without confidential information) so that we can see the rules at work and come up ones that do work.
