Assuming that you're experiencing issues with the "copyObj" function not accurately copying data from the original GUI, I have faced this issue and this is a recognized problem with the "copyObj" function.
As a workaround, you can manually copy the original values from the GUI components. After using the "copyObj" function, you can then update the values of the objects that weren't copied correctly by using the values from the original GUI objects.
% Pseudocode
ef = uieditfield(); % Create your numeric edit field
editfieldValue = ef.Value;
sld = uislider(); % Create your slider
sliderValue = sld.Value;
% code for copied objs
copiedEF.Value = editfieldValue;
copiedSlider.Value = sliderValue;
Note: Before using "copyObj" function for a GUI object, you can go through this documentation section to have a better idea of properties that might need to be set again after copying the original object: https://www.mathworks.com/help/matlab/ref/copyobj.html?s_tid=doc_ta#:~:text=expand%20all-,What%20Is%20Not%20Copied,-Tips
