Bug??? Confusion about ld_clump vs ld_clump_local

[Rick-Chen-PKU]

There are following doubts about ld_clump and ld_clump_local functions, if I have a copy of exposed data with 10 snps. I want to clump by id grouping, with same parameter setting, ld_clump and ld_clump_local give two different results, may I know why?

1. Sample data
   

2. Sample code
   

3. Sample results
   

I guess the id variable in the dat parameter of ld_clump_local seems to be disabled. Any relevant responses greatly appreciated!
