values of 10 or greater are being read as strings while below are read as numerical as i put them into my gui table

pretty much the question. here's my code

function IONS_CellSelectionCallback(hObject, eventdata, handles)
% hObject    handle to IONS (see GCBO)
% eventdata  structure with the following fields (see UITABLE)
%  Indices: row and column indices of the cell(s) currently selecteds
% handles    structure with handles and user data (see GUIDATA)
    handles=guidata(hObject);
    handles.currentCell = eventdata.Indices;
    guidata(gcf,handles);

function IONS_CellEditCallback(hObject, eventdata, handles)
% hObject    handle to IONS (see GCBO)
% eventdata  structure with the following fields (see UITABLE)
%  Indices: row and column indices of the cell(s) edited
%  PreviousData: previous data for the cell(s) edited
%  EditData: string(s) entered by the user
%  NewData: EditData or its converted form set on the Data property. Empty if Data was not changed
%  Error: error string when failed to convert EditData to appropriate value for Data
% handles    structure with handles and user data (see GUIDATA)
meq_Na = 23;
meq_Ca = 20.04;
meq_Cl = 35.45;
meq_SO4 = 48;

mg_meq = [meq_Na, meq_Ca, meq_Cl, meq_SO4];
% equi_ions = zeros(4,2);
% handles=guidata(gcf);
    Indices = handles.currentCell%eventdata.Indices(1,1)%handles.currentCell;
    if Indices(2) == 1
        data = (get(handles.IONS,'Data'));
        if Indices(1) == 1
            data{Indices(1),Indices(2)} = str2double(eventdata.NewData);
            data{Indices(1),2} = str2double(eventdata.NewData)/meq_Na;
                    set(handles.IONS,'Data',data);

using str2double to convert the values of 10 and greater to numerical, but this doesn't work for values less than 10 and if i get rid of str2double, then everything below ten works but not above. very confused as to why it is reading double digits as strings.

NVM if anyone is interested this is the code that makes it work.

function IONS_CellEditCallback(hObject, eventdata, handles)
% hObject    handle to IONS (see GCBO)
% eventdata  structure with the following fields (see UITABLE)
%  Indices: row and column indices of the cell(s) edited
%  PreviousData: previous data for the cell(s) edited
%  EditData: string(s) entered by the user
%  NewData: EditData or its converted form set on the Data property. Empty if Data was not changed
%  Error: error string when failed to convert EditData to appropriate value for Data
% handles    structure with handles and user data (see GUIDATA)
meq_Na = 23;
meq_Ca = 20.04;
meq_Cl = 35.45;
meq_SO4 = 48;
handles.meq = [meq_Na, meq_Ca, meq_Cl, meq_SO4];
guidata(hObject,handles)
% eventdata.NewData = zeros(4,1);
%     Indices = eventdata.Indices(:,1)%handles.currentCell;
e = eventdata;
if e.Indices(2) == 1
    data = get(handles.IONS,'Data');
    data(e.Indices(1),2) = (data(e.Indices(1),e.Indices(2)))/handles.meq(e.Indices(1));
    set(handles.IONS,'Data',data);
end

data_meq = get(handles.IONS,'Data');
Cat_bal = sum(data_meq(1:2,2),1);
An_bal = sum(data_meq(3:4,2),1);

set(handles.BALANCE,'string',num2str(Cat_bal/An_bal));
