Why is it normal while the hit name is not in accordance with the name used by the user in ChemACX?

The name input by the user doesn't automatically become the marquee name for the record. Many records have multiple names but only 1 will be shown in the marquee regardless of which name is used by the user. For example, "2-methyl-2-butene" as search condition, the result shows "n-amylene." Because n-amylene is another name for 2-methyl-2-butene, which appears in the synonym list for this compound if you open it.
