Error in generate_homologs

[PpGrApee]

Hello! WThank you for the nice package. I have problems when I use the following code.
ortholog_resource <- generate_homologs(op_resource = op_resource, target_organism =10090, columns = c("source_genesymbol", "target_genesymbol"), max_homologs = 5)
And there is the error:
One-to-many homolog matches:
Error in mutate():
ℹ In argument: across(all_of(columns), ~recode.character2(.x, .missing_fun = .missing_fun)).
Caused by error in across():
! Can't compute column source_genesymbol.
Caused by error in recode.character2():
! No replacements provided.
Run rlang::last_trace() to see where the error occurred.

I have tried install from this PR #174, but not work.
