Problem with the multiplier block for control

Hi everybody. I'm trying to simulate a circuit with a PI PB control, the problem is when i use the multiplier block the result isn´t correct. For the purpose to explain what´s going on please look the image below. There are 3 voltage probes (V1, V2, V3).

In the simulation you can see the response of the 3 probes. So, you can see that the output of the multiplier doesn´t correspond with the real value. When i multiply V1 and V2 in the simview, it shows the real value.

This is the only part of the entire simulation that doesn´t correspond with the real values.

Does anybody know how to fix it?? I'll appreciate the help.

    Well, actually i found a bad connection and it solved the problem, anyway, it was weird 'cause the connection was "far" from this point and the multiplier wasn't doing the operation. thanks for the answer.
