Problems to upload list of genes (Drosophila) for the Joint-Pathway Analysis

Hello,
I am trying to perform Joint-Pathway Analysis to combine the differentially expressed genes from RNAseq analysis and significantly altered metabolites from metabolomics analysis.

For metabolites, I choose Targeted (compound list), KEGG ID. Here is an example of a few metabolites from my list:
C03284
C01035
C00212
C00108
C01904
C00475
C00487
C00942

Everything works well.

For genes, I choose Organism (Drosophila melanogaster), Official gene symbols. Here is an example of a few genes:
Dmel_CR44289
Dmel_CR45314
Dmel_rst
Dmel_CR44035
Dmel_Sodh-1
Dmel_CG14500
Dmel_LManIII
Dmel_Cyp12d1-p
Dmel_CG30287
Dmel_PGRP-SB1
Dmel_CG31465
Dmel_CG34433
Dmel_TpnC47D

I get a mistake: " * Error No gene hits!".
However, if I go directly to KEGG and enter my full list, I get 20-30 hits among metabolic enzymes.

Could you please help me to find where my mistake is?
Thank you,
Andrey
