If I am understanding you properly, and you have a long HTML output where you need to fix the 5th analysis, you need to re-run the analysis program that produced all of the long HTML output, making the fixes in there.
To explain what is happening, when you use ODS HTML (or other ODS destination), SAS creates a file containing all of the outputs you just created by sending everything to an HTML file (or other file). It also creates a set of indexes, which is what you are seeing on the left of the Results window, these let you navigate quickly to parts of the output HTML file. Deleting the index has no impact on the HTML file, it only prevents you from navigating there using the Results window. So if you want the fifth analysis in the HTML file to change, you have to fix the program that created the HTML file, and then re-run it.
