I'm not sure I see where the inconsistency is. Could you explain where you see the issue?
If you want to try to fix it, add a new tab/page to the SS by clicking on the + sign at the bottom left of the SS. You will need to copy the first 2 rows and paste them to the new tab. If you click on the bucket icon, at the bottom of the color menu it says, "conditional formatting." Click on this and a dialogue box will open. You will need to then block the SS by sections (i.e., the AMPS column, the section between the dose or U column and PMPS, and then everything after the PM dose column) and specify the conditions for formatting. In other words, >500 you click on the black for numbers above 500 to be coded black, then between 400 - 500 you click on red, etc.
