Reference metabolome failed to upload

Hi! I finished statistical analysis module, then moved on to enrichment analysis with the significantly changed metabolites which i obtained from stats analysis.

I have problem while uploading my own reference metabolome under the enrichment analysis modulue. I got the error message saying that half of my compound cannot be matched to our database. but I used the compound names I got from the name conversion tool

my reference metabolome and the significant metabolites list can be found attached.
what could be the reason?

Thanks!
Taolin
