Error: Duplicate ID '26:42' generated by --set-missing-var-ids.

Question

I used the command below to update variant information, but something went wrong, it seems that my vcf has 2 variants in the same position.

 :~/Documentos/PLink_Manu$ 
      plink --file dis-MT --set-missing-var-ids @:# --recode --out dis-MT
       PLINK v1.90b6.10 64-bit (17 Jun 2019)          www.cog-genomics.org/plink/1.9/

              --recode
              --set-missing-var-ids @:#

        Error: Duplicate ID '26:42' generated by --set-missing-var-ids.

so I used the following command:

 plink --file dis-MT --set-missing-var-ids @: # [b42] \ $ 1, \ $ 2 --recode --out  dis-MT

but the following error appeared:

Error: The --set-missing-var-ids template string requires exactly one '@' and
one '#'.
For more information, try "plink --help <flag name>" or "plink --help | more".

what should I do?

Remove all the spaces from the middle of the --set-missing-var-ids argument.
