Error Code: "A viewer named "DAS" already exists"

I am trying to run my script and call a simulation. But everytime I run it, the beginning variables save but I get this error:

>> run_2_probe_cases_test13_Temp_perturb Error calling slsfnagctlr('Clear',...) A viewer named "DAS" already exists. Error using run_2_probe_cases_test13_Temp_perturb (line 119) Invalid setting in 'RF_Ablation_Model_T_perturbed_2_probes/Thermal Dynamics/Probe 2/Probe dynamics y1/Probe Lump 1/Subsystem/Constant3' for parameter 'Value'

Caused by: Error using run_2_probe_cases_test13_Temp_perturb (line 119) Error evaluating parameter 'Value' in 'RF_Ablation_Model_T_perturbed_2_probes/Thermal Dynamics/Probe 2/Probe dynamics y1/Probe Lump 1/Subsystem/Constant3' Error using run_2_probe_cases_test13_Temp_perturb (line 119) Undefined function or variable 'time_step'.

I have no idea what this means or how I can fix it.

Any suggestions would be helpful!

For those who are having the same issue, restarting MATLAB eliminated this error for me.
