I'm getting an error "Reference to non-existent field 'x_440V_Tripped' when attempting to load a CAN log file from a simulation and examine the contents with "canMessageTimetable" and "canSignalTimetable"

The signal within the message is defined as '_440V_Tripped' (with no preceeding 'x' It has the underscore as the CANdb spec does not allow digits as the first character). The database can be successfully parsed and used to configure a "CAN pack" block and creates a file via CAN log. Other messages containing other signals defined in the same database are fine.

Reference to non-existent field 'x_440V_Tripped'.

Error in canSignalTimetable/makeIndividualSignalTimetable (line 119)

signalTimetable.(signalNames{jj}) = [signalStructs.(signalNames{jj})]';

Error in canSignalTimetable (line 74)

signalTimetable = makeIndividualSignalTimetable(messageTimetable, messageNames);
