Matlab is showing error even after correcting shadowing error

I have corrected the shadowing error but Matlab is still giving warning that it hasn't

Also the visualisation is not coming.

version is R2019b

It doesn't appear that you've corrected the shadowing warning which is that your model is call robotController.slx when there is already a matlab file called robotController.slx.

To completely get rid of this warning rename your file to something else (that is not already used).

Its working now ,thanks

But I had shadowed the other matlab file earlier as you can see in the image and had loaded the required model.

why was it earlier giving error than ?
