Error: none of the given SNPs can be matched to the genotype

I'm having trouble getting gcta to match the list of variants from my conditional list to the genotype and summary file, although it looks like the SNPs are written the same way in each of the files. 
As an example, here is one variant "1:25768937" which is listed in the genotype, the summary, and the conditional SNP list:

$ grep 1:25768937 AF5.chr1.bim
1 1:25768937 0 25768937 A G

$ grep 1:25768937 AA.HDL.CurSmk.Int.1.txt
1:25768937 A G 0.2875 -0.0036 0.0073 0.6239 23748

$ grep 1:25768937 Known.Conditional.txt
1:25768937


The output that I receive is pasted below:

I can't think of what else to check to see why these aren't matching.  Any ideas?
