Framemaker 2020 - Conditional Tags provided that cannot be deleted

I loaded Framemaker 2020 and everything is going smoothly except the following two conditional tags are provided by default:

• FM_PDF_Comments_Highlight
• FM_PDF_Comments_Underline

Since I use conditional tags all the time for my work, the last thing I want is two more tags. However, no matter how hard I try, I cannot get rid of these two. I delete them, they seem to be gone, save the file, but when I open the file again they are there again. Does anyone know how to permanently get rid of them. I have lots of manuals and I do not want them in every file in every manual.   thank you
