MATLAB: <1x1 struct> unsupported class

save scriptstructure

Hello!
I am dealing with the following:
I have a script, which I run and at the end of the script all the variables are written in a .mat file using the command 
MatFilename = [folder,92,system_name];
save(MatFilename);
while an already existing .m file with the same variables is being updated using the command 
mFilename=[folder,92,system_name,'.m'];
matlab.io.saveVariablesToScript(mFilename,'SaveMode','update','MaximumTextWidth',200, 'MaximumArraySize',10000);
Now, in the original script I have the following:
OL_TTable=cell2struct(TT,Tstrings,2);
which in the workspace gives something like this:
OL_TTable = 
  struct with fields:
    Tstrings1: ["41"    "Wavelength"    "RS"    "dRS"    "qRS"    "RP"    "dRP"    "qRP"]
    Tstrings2: ["82"    "Wavelength"    "RS"    "dRS"    "qRS"]
    Tstrings3: ["41"    "Wavelength"    "RS"    "dRS"    "qRS"    "RP"    "dRP"    "qRP"]
    Tstrings4: ["40"    "Wavelength"    "RS"    "dRS"    "qRS"    "RP"    "dRP"    "qRP"]
    Tstrings5: ["39"    "Wavelength"    "RS"    "dRS"    "qRS"    "RP"    "dRP"    "qRP"]
    Tstrings6: ["38"    "Wavelength"    "RS"    "dRS"    "qRS"    "RP"    "dRP"    "qRP"]
    Tstrings7: ["37"    "Wavelength"    "RS"    "dRS"    "qRS"    "RP"    "dRP"    "qRP"]
In the output .m file, instead of that, I get the following:
    OL_TTable = saveVarsMat.OL_TTable; % <1x1 struct> unsupported class at OL_TTable.Tstrings1
and at the same time I get this warning on my workspace:
Warning: The variables that could not be saved into MATLAB script are saved
into MAT-file 'D:\Mulprod\MulProd723\MulProd7231\newOL_COM_KK\Test01.mat'.
Does anyone know how I can write the structure OL_TTable directly on the output m.file?
Thanks in advance for your help!

Class string is considered a MATLAB object, it appears.
You might have to convert to cell array of character vector.
