Some GC-MS peaks donot correctly aligned

Hello,

I found that some GC-MS peaks do not align correctly. For example, benzaldehyde and 1.2.4-trimethylbenzene have quite difference spectra according to the NIST library, however they are aligned as one peak and only 1.2.4-trimethylbenzene is reported even though I have set 80% spectrum similarity for the alignment (please see the attachment). Does anybody know what is wrong here?


thanks in advance.
