Fuzzy matching issues for merging two datasets with reclink command

[Vernika Mrig]

Hi

I am trying to match two datasets using the reclink package, using the following code:
reclink mandal_village_clean using "xyz.dta", idmaster(idmaster) idusing(idusing) gen(score) minscore(0.8)

but I get this result:
9920 perfect matches found

Going through 6621 observation to assess fuzzy matches, each .=5% complete
option ( not allowed
r(198);

and I'm not able to figure out why this is happening.

Can someone help me with this?
