When you have COILS software, it's required to flag some options to preserve some customization.
You have to flag some option if:
1- "Preserve all customizations": for example, if you have received specific customization from UNILAB, you have to flag it
2- "Preserve printouts": if you have modified the printout using PageBuilder software by yourself or if you have received from UNILAB customized printout, you have to flag it
3- "Preserve translations": if you have modified the translations using the Excel file in the main COILS installation folder, you have to flag it
