why are binary variables appearing out of nowhere after pre-solve in gurobi?

I am trying to solve a fairly large MIP model in gurobi. I am using a '.lp' file as the input to gurobi.

My problem has continuous and integer variables. But no binary variables

while solving the model on the gurobi command shell.
enter image description here

why are binary variables ( 93 of them) being created after pre-solve ?

Some of the integer variables may have bounds of [0,1], before or after presolve.
