Adding rugby rapid cement to cement/sand mixture

I mixed rugby premium cement with sand to make a small capful (small cap off an aerosol can) of sand cement mixture

I then added a few table spoons of rugby rapid set cement to the mixture

I have applied this mixture to a bathroom wall to fill a very small hole in the corner of a wall

Can someone please tell me if mixing in the rapid set cement will have Any negative effect on the mixture please
I am worried and think I shouldn't have added the rapid set cement

Thank you
