Variables in workspace are not appearing in workspace window

I've been having this issue where after running a .m file or a simulation in simulink, the variables are not appearing correctly in my workspace window. For example, if I run a script that says a=1; My workspace window will show nothing, but if I type a, I will see its value. Then if I run the script again it will appear, but with the value it had before.

Ex.

run script,

 a=1;

the workspace appears empty

type a in the command window, it shows

 a =

     1

run script

 a=2;

the workspace shows a as 1

type a in the command window, it shows

 a = 

     2

Has anyone had a similar bug?
