Error in Simulink Design Verifier Compatibility Analysis

I am using Matlab 2018b and i hade this error:

The inport block 'Single_Baro_Altimeter_Environment_V3/Subsystem1/Single_Baro_AltimeterOutBus' is directly connected to outport 'Single_Baro_Altimeter_Environment_V3/Subsystem1/VNE_Alert' and therefore cannot accept a signal with elements of differing data types. This can be usually fixed by inserting a Signal Conversion block with the 'Signal copy' option selected, at the output of the inport block 'Single_Baro_Altimeter_Environment_V3/Subsystem1/Single_Baro_AltimeterOutBus'. Alternatively, if this input port is within a function-call subsystem, consider checking the 'Latch input for feedback signals of function-call subsystem outputs' option.

VNE_alert is a Boolean variable.

knowing that at first, I put the 'VNE_Alert' port's type as Enum: State, which is wrong of course, and when I correct it and I put it Boolean, or simply Inherit: auto, I had the same error message when I put a wrong type.
