Different result using an initial basis

Hello,

I was using gurobi in order to solve some linear problems and I found something which I do not understand. The issue is the following: I solved a problem using gurobi and I obtained 6.601723419e+01 as optimal value. However, I loaded a .bas file in order to set an initial basis and I obtained 7.000861317e+01 as optimal value.

Any idea why this happens? The problem file could be downloaded from https://www.dropbox.com/s/o8f95f29vvevvhv/problem.lp?dl=0 and the basis file from https://www.dropbox.com/s/9l07eplky2nf0ob/basis.bas?dl=0

Thank you in advance for your time.
